By Charles Morgan and Hubert Walker for CoinWeek Notes …..

After three years of Special Mint Sets and the transition from silver coinage to clad coinage, the United States Mint softened its anti-collector position and reintroduced its annual Uncirculated Coin Set and Proof Set programs. In what was a big change for Proof coinage, production shifted from the Philadelphia Mint to the United States Assay Office in San Francisco (formerly the San Francisco Mint). Proofs struck at San Francisco carry the S mint mark, and outside of a notable few Branch Mint Proofs issued in the 19th century, these were the first standard Proofs not struck in Philadelphia.

The coin-collecting public got their first glimpse of the sets on January 4, 1968, at a ceremony at the Denver Mint to mark the return of mint marks to United States coins. On display were two of the 1968-S Proof Sets.

Collectors and dealers hotly anticipated the new Proof Sets and purchased 3,041,506 sets at a cost of $5 each, which, in 2024 inflation-adjusted dollars, was $44.59. 1968 Proofs Sets sell for about 1/5th of that price, and largely only because the 1968-S Kennedy half dollar contains a little over $4 of silver (based on April 8, 2024 spot prices).

The 1968-S Kennedy Half Dollar – Collector Characteristics

The shift in production from the Philadelphia Mint to the San Francisco Assay Office did not lower the quality of the Proof coins. The new sets were packaged in an improved plastic hard case, allowing for easy viewing of the obverse and the coin’s reverse. This hard case fit snugly inside a royal blue cardboard envelope, on which UNITED STATES PROOF SET · 1968 was written in white letters at the bottom of the front side.

The Kennedy half dollar Proof was one of five coins included in the set. As a 40% silver-clad coin, the half dollar was noticeably brighter in appearance than the Jefferson nickel, the clad Roosevelt dime, and the Washington quarter. Most collectors would find their Proof coins to be brilliant when examining the sets. Occasionally, coins struck very early in a die’s deployment would exhibit some degree of Cameo frost. Only coins struck immediately following the deployment of freshly prepared obverse and reverse dies will exhibit Cameo on the obverse and reverse. Cameo 1968-S Kennedy half dollars are uncommon for this date, and Deep/Ultra Cameo examples are scarce.

It’s been more than 50 years since the 1968-S Proof Set was issued. Even though the case was an improvement over the soft packaging of the pre-1965 sets, the plastic sleeve was not airtight. Because of this, it is not unusual for these coins to tone or develop a light haze. The haze can be removed with professional curation.

What Is a 1968-S Kennedy Half Dollar Worth?

To adequately answer this question, one must first establish the following criteria: is the goal to have one unimpaired Proof example, or is the goal to have a certified coin, preferably in high grade with Cameo or Ultra Cameo contrast?

If the answer is the former, then 1968-S Kennedy half dollars can be readily purchased for the cost of a 1968-S Proof Set, which is to say $10 to $15. With the purchase of the set, you get Proof versions of all five circulating coins released in 1968.

If the answer is to have a certified high end coin with Cameo or Deep/Ultra Cameo, then the cost of acquisition escalates dramatically.

Market Data and Noteworthy Specimens

Top Population: PCGS PR-70DCAM (16, 4/2024). NGC PF-69UC (716, 4/2024), and CAC None Graded (0:0 stickered:graded, 4/2024).

What’s interesting about the reported 16 coins in the PCGS PR70DCAM census report is that at least 15 of these coins was from one bulk submission. This submission yielded mostly PR69DCAM or PR70DCAM coins with some PR69CAM coins as well.

Beyond the coins listed in our auction data are certs 7733372, 7733374, 7733375 (Del Loy Hansen coin), 7733379, 7733380, 7733384, and 7733386. Auction data for these cert numbers begins to appear in the early 2000s.

The question is, where these coins accumulated in a major dealer effort to promote DCAM 1968-S Kennedy halves, and if so, how did they acquire nearly all of the perfect coins available? And why have no additional coins surfaced at this grade in the years since?

4,500 canceled dies used to strike 1968-S Proof Sets were sold into the collector market, presumably as scrap. After discovering this, the Mint invested over $50,000 in equipment to melt all future dies. New England Rare Coin Galleries sold several of these dies in 1974 at $24 each or 10 for $225.
