How to Buy Rare Coins on eBay Auctions

This article distills the lessons gleaned from my ten years of experience as an active buyer and collector of rare coins on eBay auctions. Over that period of time, I’ve made many mistakes, and you, the reader, will benefit from this by hopefully avoiding making these same mistakes. My goal is to help you have a better buying experience on eBay, by buying as many coins as possible that are genuine, original and worth the prices paid. Also, although the target environment is eBay, these strategies can be easily adapted to other auction venues – Heritage, Stack’s-Bowers, etc.

Some Expertise

ebay auctionsI am assuming that you know how to use the eBay search facility to locate listings of coins that are of interest, that you know how to track these listings using the “Watch this Item” facility within “My eBay,” that you are familiar with the mechanics of bidding, and that you have at least some rudimentary ability to grade the types of coins that are of interest to you. However, if you need any help with any of these features, contact me thru the E-Gobrecht editor and I will try to help you out.

Terms of Art

One term used to describe a rare coin is that it is “Original.” In U.S. numismatics, “original” means that the coin has not been cleaned, tooled, re engraved or messed with in any way, and that any departure of the coin from its mint state has happened naturally, in the form of circulation wear and toning. Buying a coin that is original and problem free should always be your goal.

Conversely, in European numismatics, and occasionally in the U.S., the term “Original” is used as a synonym for “Authentic.” I always use “original” in the U.S. sense. To convey authenticity, I use either “authentic” or “genuine.” When you come across an eBay listing of a coin that is described as original, it is important to understand which meaning applies. Sometimes, but not always, the seller’s meaning is clear from the context. If it isn’t clear, you can ask him.

Why Original?

Why is it important to stick to original coins when at all possible? Because the rare coin market says they are worth more. They are the only coins that PCGS and NGC will grade and encapsulate
All other things being equal, an original coin is simply worth more than one that has been cleaned or has some other problem. PCGS (Professional Coin Grading Service) will encapsulate a coin that is genuine but not original. However, they won’t grade it. NGC will only encapsulate it under their NCS service. ANACS will grade a coin that is not original, and will assign it a “Details” grade.

Getting Started

So let’s assume you have located an eBay listing of a coin that you are interested in. How should you approach it? First, you want to know if the coin is original and problem free. If the coin has been certified by PCGS or NGC, you know it was the grading service’s opinion that the coin is original. That counts for a lot.

If the coin was graded by ANACS (not a details grade), you know that ANACS thought the coin is original. This counts for something, but less than if the coin was graded by PCGS or NGC, as I have seen too many ANACS graded coins that have been cleaned.

But suppose the coin is raw. How do you tell if it is original, assuming the seller says nothing about originality in the item description? Unfortunately, even with a very good photograph under natural light, it is unlikely you will be able to tell if the coin is completely original and problem free. So your first step should be – ask the seller! The way I like to ask the question is as follows: “Has this coin been cleaned or had anything else done to it that would prevent it from being certified by PCGS or NGC?”

I ask the question this way regardless of whether or not I intend to get the coin certified. Note that what you are asking for is an opinion, not a guarantee that the coin will slab. How the seller responds to this question has a very important bearing on whether I will bid on the coin or not. Here are some of the responses I have gotten in the past.

1. I have no idea, I’m not an expert.
2. I didn’t clean it. I don’t know what happened to it before I bought it.
3. It may have been cleaned, I’m not sure.
4. It’s been cleaned. PCGS won’t certify it.
5. It hasn’t been cleaned and doesn’t have any problems. It should certify.

If the seller states point blank that the coin has been cleaned or has some other problem, I move on and look for another coin. You might be surprised how many sellers know about a coin’s problems, won’t mention them in the auction listing, but will cheerfully disclose the problems when asked. If the seller says the coin hasn’t been cleaned and will certify, I make my plans to bid, however I seldom get this response.

You will often get responses #1, #2, or #3 above, because many sellers are not professional numismatists, and simply don’t know what to look for to determine originality. Characteristics of cleaned coins include (1) the coin has a washed out, pasty look; (2) the coin is below AU in grade but is “white”, i.e. has no tone; (3) the coin has odd, unnatural looking tone (also a characteristic of artificial toning); (4) the coin has hairlines, indicating a cleaning. Unfortunately, it is very difficult to tell from a typical auction listing photograph whether or not a coin has any of these characteristics, which is why it is so important to have a return privilege.

Return Privilege and Photos

In U.S. numismatics, many if not most professional coin dealers offer an unconditional return privilege of from 3 to 30 days when they sell on eBay. (Sometimes, a return is not offered on coins that are certified.) The theory behind the return option is that, even with a photograph, you can’t really tell what a coin looks like until you get it in your hand.

For this reason, when I buy coins on eBay, I usually try to avoid coins where the seller does not offer a return privilege. Only when I am relatively certain about exactly what I am buying (for example the coin is certified), do I depart from this rule.

Having a return privilege is a powerful way to control your risk. When offered, a return option limits your risk to a round trip of shipping expenses. It allows you to bid in situations where you wouldn’t dream of bidding without it.

Have you ever seen a listing of a coin with a photograph that was so bad that it was like having no photograph at all? Your initial reaction might be not to bid, but if a return option is offered, and the coin seems from the description to be just what you are looking for, go ahead and bid. You are likely to win it for a lot less than if it had a good photograph, because a bad photo inhibits other bidders. The converse of this principle is also true. That is, when the coin’s photo is really good, showing all of the detail and the natural color of the coin, then bidding is likely to be very heavy. I sometimes find myself avoiding these listings simply because the bid price gets too high.

As far as the number of days for the return option, even one day is long enough for me in most instances, because I usually know within a few minutes of receiving a coin whether I want it or not. In those instances in which I decide to return a coin, as a courtesy I notify the seller immediately by email of my intent, and I put the coin back in the mail the same day I receive it.

Getting Coins Certified

I get most of the raw coins I buy certified by PCGS, or occasionally by NGC. Although I would like sellers to guarantee that their coins will certify, few sellers are willing to do so. However, if the return period on the coin is 30 days, that is long enough for me to submit the coin to PCGS under the “regular” service, receive it back from PCGS, and, if it doesn’t certify, return it to the seller.

This issue is most important to me when we are talking about very expensive, raw coins. In this case, when the return period stated in the listing is less than 30 days, I try to negotiate with the seller (before I bid) an extension of the return period to 30 days.

Also, I’ve found it best to be completely up front about what I am doing. That is, I tell the seller that I plan to submit the coin for certification, and return it if it doesn’t certify. I also tell the seller that my return is contingent on the coin grading or not grading, not on the numerical grade that PCGS assigns.

In other words, if PCGS grades it, I keep it, regardless of whether it comes back, for example, a VF35 or an XF40. I do this because I feel that the major risk is of the coin not grading at all, much more than the risk of getting a grade other than what I expected. I find that sellers are more apt to go along with me if the contingency is constructed this way.

Besides cleaning, there are other things that will prevent PCGS from grading a coin, for example artificial toning, rim bruises, scratches or any other type of damage. These problems are usually obvious from a decent photo, unless they are very minor. And if they are very minor, PCGS may go ahead and grade the coin.

Other problems include re-engraving (where someone tried to reestablish detail that had been lost from circulation wear), and tooling, usually performed in an attempt to “fix” a scratch or other problem. These latter two problems I find very difficult to identify. But fortunately, my experience has been that they don’t occur all that often.

Bidding – the Hidden Reserve

One of the more irritating things that sellers do is to place a secret reserve on a coin’s listing, with the opening bid some lower amount. Instead of a reserve of $500, you would think that they could simply make $500 the opening bid amount. The theory is that allowing bidders to bid below the reserve stimulates bidding activity. My suspicion is that just the reverse is true, that is, I believe that hidden reserves tend to inhibit bidding.

There is however a simple solution, which can actually turn this situation to your advantage. That is to simply ask the seller what the reserve amount is. My experience is that 80% to 90% of the time, sellers will respond to an email by disclosing the reserve amount. This is particularly true if the listing has run for a while with little or no bidding.

Once armed with the reserve amount, you can plan your bidding strategy. If the reserve amount seems to be reasonable, you can bid it. If it seems to be too high, you can plan to let the listing end, and then, if no one has won the coin, you can make the seller an offer at some price below the reserve amount.

In the latter situation, I will typically make the offer (using “Ask the Seller a Question”) a few minutes before the listing ends, due to the fact that eBay makes it difficult to contact the seller for an expired listing. If the seller likes your offer, it is simple enough for him to re list the coin with a “Buy it Now” at your price.

Bidding – to Snipe or not to Snipe

There are at least three schools of thought when it comes to bidding strategy.

The first is a “one-bid” strategy, and it is to bid as early as possible with the absolute highest amount you are willing to bid for the coin, and then to sit back and wait for the auction to end.

The second strategy is to bid early and low, then if you are outbid, bid a little more, and if you are outbid again, bid a little more, etc., etc. I find this to be a common strategy with novice bidders (i.e. low feedback score).

The third, also a one-bid strategy, is to bid the highest amount you are willing to go a few seconds before the listing ends. This strategy is referred to as “Sniping.” After ten years of experience, I can state unequivocally that sniping is the best strategy, because it affords you the maximum chance to win the coin, and at the lowest possible price.

The key aspect of sniping is that because your bid is made with only a few seconds left on the listing, nobody has a chance to bid in reaction to your bid. Thus sniping protects you against bidders employing bidding strategy number two. If you bid at any time other than a few seconds before the auction ends, bidder number two will see your bid and decide he can go a little higher, which can only have two possible results, both of them negative. Either you will be outbid, or else you will not be outbid, but will end up paying a higher price for the coin.

Conversely, sniping prevents bidder number two from reacting to you because he has no time in which to do it. Sniping also protects you against some of the bidders employing strategy number one. That bidder thought he was bidding his highest possible bid, and expected his bid to prevail. When he sees your bid, however, he decides he can go a little higher. Again, the key to sniping is that it prevents anyone from reacting to your bid by bidding again.

Bidding –

What Price to Offer or How High to Bid There is no hard and fast rule about how high to bid or offer for a rare coin. Part of the answer is very personal (How badly do you want it?). But even if you desperately want a particular coin for your collection, and you are willing to pay some premium, you still want to know that you haven’t paid substantially too much.

For U.S. coins, there are retail pricing guides that provide some guidance. These include the Red Book, PCGS Price Guide, and Numismedia. The only price guide I am aware of for World coins is Krause, but I find Krause’s prices to be out-of-date most of the time and therefore of limited use.

For U.S. coins there is a good bidding strategy that relies on the pricing guides. This is to use the guides to determine what a coin is worth, and then bid 10 to 20 percent above this value. You can feel better about this strategy if you try to limit it to coins which you feel for some reason (e.g. outstanding toning, pedigree) are worth a premium over retail.

The reason this strategy works is that there are a substantial number of bidders out there who adhere to the price guides pretty strictly, and won’t bid above them. So by going 10 to 20 percent above the retail price, you eliminate a lot of the bidding competition.

You will notice that I refer to retail pricing guides and have not mentioned wholesale guides like Greysheet. My experience has been that most bidders use retail guides, and not wholesale guides, to base their bidding strategy. Consequently, if you base your bidding on Greysheet, you will likely be outbid most of the time.

For gauging how high to bid for world coins, I am afraid there is no substitute for experience. I rely on Krause not to decide how much to bid but to establish a ballpark or an order of magnitude, i.e. is this a $300 coin or a $3,000 coin. To decide how much to bid on Russian rubles, I rely on my years of experience, and auction records. I also rely on one dealer and three or four other collectors for advice, all of whom know much more about rubles than I do.

Avoiding Counterfeit Coins

Although there is no absolutely foolproof way of avoiding bogus coins, there are a few things you can do to protect yourself. First, in the case of coins sold within the U.S., the Hobby Protection Act requires any non-genuine coin to be stamped “Copy” on either the obverse or reverse. In my ten years of collecting and bidding on eBay, I have only been stuck with one counterfeit U.S. coin that I know of, a bust dollar, and I didn’t know it was counterfeit for five years after I bought it. When it came time for me to sell it, ANACS gave me the bad news.

Since I had bought the coin from a reputable U.S. dealer, and since virtually all reputable U.S. dealers offer a lifetime guarantee of authenticity, I was able to recoup my purchase price from the dealer from whom I bought it. However, I lost all of the profit from the increase in price that the coin would have generated had it been genuine, which was thousands of dollars.

The key to avoiding most counterfeits is to always consider the source. Thus, there is a dealer from China selling Russian rubles (which I collect). He has recently listed five 18th century rubles, all of them rare issues worth thousands, each with an opening bid price of $49.95, each offered with no reserve. Red flag? Of course, this is an easy one. Think to yourself, “where could he have gotten them?”

There is no good answer. Even without the knowledge that there is a flood of well made counterfeit coins emanating from China, this is an easy one to detect. I’ve gotten to the point that I simply will not bid on any coins listed by sellers located in China. It simply isn’t worth the risk. Thus my key for avoiding counterfeits is to try to avoid high-risk sellers. This is because I don’t have the skill to detect a well made counterfeit coin after I have it in hand. That’s the job of the grading services. I know you can weigh it and do other things, but I prefer to rely on a strategy that keeps you from buying likely counterfeits (consider the source), rather than a strategy that detects counterfeits after you have already purchased them.

Despite the strategy of “consider the source,” there may come a time that you purchase a coin whose authenticity is in question. This happened to me a couple of years ago when I purchased a ruble for about $900 from a seller in Romania. I should have simply not bid on the coin because I was somewhat suspicious concerning authenticity, but it was a date I really wanted, so I bid anyway, and won the coin.

However, before I bid I contacted the seller and told him that if I won the coin, I would be submitting it to PCGS and would be returning it if it turned out to be a fake, and without his agreement to accept these terms I would not bid. Of course the seller assured me that the coin was genuine (based on what?). PCGS however, ruled the coin was counterfeit, so I returned it, and thus limited my loss to two round trips of shipping expenses – not a small amount, but nowhere near $900.

Then there is the seller in Germany selling on the German eBay web site, He sells rubles which he claims he found in his garage, so he knows nothing about them and therefore cannot guarantee their authenticity. What a story!

Of course I believe he knows darn well his coins are bogus, and tries to prey on buyers who will buy his coins in the hopes that they are genuine. It is a cardinal rule that I will not bid on or buy a coin from a seller who will not guarantee authenticity.

Negotiating the Price

Whenever a seller lists a coin that I want with an opening bid amount or a reserve that is substantially above the market price, I see an opportunity for negotiation. When I see this situation, I expect the coin not to sell during the auction process. Some-times I will wait until the listing has almost run out of time (See Bidding – the Hidden Reserve above), or sometimes I will send an immediate email to the seller, which states “If this coin does not sell, I would like to offer X for it”.

Both the substance of my lowball offer, and the fact that the offer is made early in the listing sends a message to the seller, without stating it explicitly, that I consider his Opening bid price/Reserve price/Buy-it-now price to be way too high for the market, and that he shouldn’t expect to realize much more than I am offering. Of course someone may still bid and make me look a little silly, but more often than not no one bids, and the negotiation begins.

In this situation, you should never be afraid to make a lowball offer for fear of insulting the seller. And it is this initial offer that is critical to a successful negotiation. Likewise, the seller’s initial response to your offer will tell you pretty clearly if you have gauged the situation correctly, and whether or not the negotiation is going anywhere. If the seller responds with a counter-offer that is only a token amount below his initial price, then either he has not given up on getting a huge profit, or else he paid way too much for the coin himself, and is now stuck. (There is a third possibility, namely that you do not have as firm a grip on the market as you had thought.) Whatever, the negotiation is now over.

If on the other hand, the seller counters with a price that is substantially below his initial price, you have basically won the negotiation. It is now only a matter of either accepting the counter offer, or countering yourself to try to get the price even lower. I just completed a negotiation for a ruble being offered by a seller in Luxembourg for a buy-it-now price of $650. My sense was that this coin was worth somewhere in the $300-$400 range, so I made an offer of $325, exactly half of asking price. The seller countered $440, I countered $350, the seller countered $415, I countered $375 (my last offer, since eBay for some curious reason will not allow you to make more than three offers), the seller countered $390, and I accepted. That’s 40% below the initial buy-it now price.

  1. As far as buying/saving $ and eBay goes:

    If you send the seller a question about an item, find another of their listings, and send the question from that item page, rather than from the one that you actually want. This will add a little bit of work for the seller, if they want to add the question/answer to the item description page that you are actually interested in.

    If you see an item that you want listed in auction format, send the seller a message asking if they will accept $x to end the auction early and sell the item to you. May be telling them that they would not have to wait as long to get their money (they would probably know that, but it still might help). If that does not work, use a sniping service such as to bid for you. It’ll bid in the last few seconds, helping you to save money and avoid shill bidding.

    Use a site like to set up saved searches. You’d get an e-mail whenever a match is listed. Especially good for “Buy It Now”s priced right.

    If the item that you are looking for is difficult to spell, try a misspelling search site like to hopefully find some deals with items that have main keywords misspelled in the title. Other interested buyers might never see them. Then, if the item is listed an auction format, after a few days of no bids (hopefully anyway) send the seller and offer to end the auction early and sell the item to you. They may worry that no one is interested, and take whatever they can get.

  2. I have read and re-read the coin week articles on ebay practices. I finally decided to bid on an auction using a sniping service. My bid went in with 21 seconds left on the listing, but I was not the winning bidder. According to the listing, I should have been. My “snipe” bid was $ 15.51 on an auction where the winning bid was $ 15.01. When I called eBay to find out why I had not won the auction, I was told that sniping services were against eBay rules. Comments anyone? Thanks

  3. Regarding using Retail or Wholesale Price Guides for information on setting your bid price, Ebay now allows you to review recent auctions or BuyitNow sales. If the coin is not rare you can see what the recent winning bids are to get up to the minute information on what others are willing to pay for the coin. The ‘Completed Listings’ filter box is on the left side of the search screen under the ‘Show Only” heading.

  4. I have bought quite a few coins off of eBay and have employed all 3 bidding practices. Sniping has worked for me a couple of times but what I really liked about the article was contacting the seller as opposed to just waiting to see what happens with the bidding. I certainly learned a lot from your article! Thanks

  5. What about using Proxy bidding on ebay? You simply let ebay know what your max bid is. This is kept secret. And if ebay can win the auction for you for less than your max bid, it will.
