CAC Coin Premiums Result in Impressive Auction Prices for September
Two gold coins carried the same date and grade. Both came from the same legendary American coin series. Yet one sold for more than four times the price of the other.
That striking difference emerged during September 2026, as CAC-approved and CACG-certified coins attracted strong bids at several major auction houses.
The results offer a fascinating look at CAC coin premiums and how collectors judge quality. In some cases, bidders paid substantially more for coins with CAC approval than for comparable examples without it. Even more revealing, one early American silver dollar nearly doubled its previous auction price after gaining a CAC sticker.
CAC has highlighted 12 such transactions from September. The coins range from a rare Civil War gold piece to a modern silver medal. Together, they tell a broader story about quality, collector demand, and the prices buyers will pay for exceptional coins.
Heritage Auctions: A Rare Stella and Two Remarkable Gold Coin Comparisons
Heritage Auctions opened September with several noteworthy examples of the market’s appetite for CAC-certified gold.
Among them was an extraordinary 1879 Flowing Hair Stella, the unusual $4 gold denomination that Congress considered during America’s experimentation with international coinage.
The Stella emerged from a proposal to create a gold coin that could compete in international trade. Its unconventional denomination and distinctive composition reflected an effort to bring American gold coinage closer to European monetary standards. Congress never authorized the denomination for regular circulation. Nevertheless, the surviving pattern coins became prized American numismatic rarities.
On September 2, Heritage sold a CACG-certified Proof-66 Cameo example for $292,800. Interestingly, a PCGS Proof-67 Cameo specimen without CAC approval had brought $288,000 at Stack’s Bowers on November 11, 2025.
The lower numerical grade brought the higher price. Although the two coins sold months apart and differed in individual characteristics, the comparison demonstrates why sophisticated buyers look beyond the number on the holder.
An even more dramatic result involved an 1864 Liberty Head quarter eagle, a $2.50 gold coin from one of the most turbulent periods in American history.
The Philadelphia Mint produced only 2,824 quarter eagles in 1864. By then, the Civil War had driven gold from everyday circulation. Hoarding and melting claimed much of the nation’s gold coinage, and relatively few examples of this particular issue survived.
Heritage estimates that only 18 to 22 circulation strikes remain today.
On September 2, a CAC-approved PCGS AU-50 specimen realized $100,650. Just one day earlier, Stack’s Bowers sold an NGC AU-50 example without CAC approval for $36,600.
That enormous difference underscores the importance of individual coin quality in a series where collectors have few opportunities to acquire genuinely desirable survivors.
Finally, Heritage offered one of the month’s most revealing side-by-side comparisons.
On September 2, two 1924 Saint-Gaudens double eagles crossed the auction block in successive lots. Both carried PCGS MS-67 grades. However, only one had CAC approval.
The CAC-approved example brought $47,580. Its non-CAC counterpart realized just $11,285.
The contrast becomes even more interesting when considering the coin’s history. The Philadelphia Mint struck 4,323,500 double eagles in 1924, making the issue one of the most readily available dates in the Saint-Gaudens series.
Yet extraordinary preservation changes the equation. Heritage reported only 28 CAC-approved MS-67 examples at the time of the sale, with none approved at a higher grade.
For advanced collectors, that level of quality creates a different market from the one serving buyers who simply want an attractive Saint-Gaudens twenty.
Stack’s Bowers Galleries: An Early Dollar Returns With a New Distinction
Perhaps the most persuasive example from September involved a coin that collectors had already seen at auction.
On September 1, Stack’s Bowers sold an 1801 Draped Bust silver dollar, graded PCGS AU-53 with CAC approval, for $20,740.
Less than 11 months earlier, on November 11, 2025, the auction house sold the exact same coin in the same PCGS holder. At that time, it lacked a CAC sticker and realized $10,800.
The difference amounts to $9,940.
Unlike comparisons involving separate examples, this transaction follows an individual coin through two sales. Although demand for early dollars strengthened during the intervening months, its newly acquired CAC approval represented a significant change in how buyers could evaluate the coin.
The coin itself deserves attention beyond its auction history.
Draped Bust dollars represent America’s first generation of federal silver coinage. Their Heraldic Eagle reverse reflects the young nation’s developing identity. Moreover, the Mint’s early production methods created numerous die varieties that specialists continue to study today.
This particular dollar carries the BB-211, or Bolender-1, attribution, a recognized Rarity-3 die marriage. It offers a direct connection to an era when American coin production still operated on a relatively modest scale.
Stack’s Bowers also achieved an impressive result with an 1806 Capped Bust Right half eagle, graded CACG MS-63+.
This $5 gold piece features the Pointed 6 date style and an arrangement of eight stars to Liberty’s left and five to her right. Collectors recognize the variety as BD-1.
These details matter because early American gold specialists often collect coins by individual die marriage rather than date alone. The Pointed 6 also represents a substantially scarcer variety than the more frequently encountered Knobbed 6.
On September 1, the CACG example brought $40,260. The following day, Heritage sold a PCGS MS-63+ example of the same major variety without CAC approval for $35,380.
The difference was more modest than some September results. Still, it reflected continued demand for attractive early gold in a challenging Mint State grade.
The auction house recorded another strong sale with a 1910-S Indian Head half eagle, graded PCGS MS-64 with CAC approval.
Sculptor Bela Lyon Pratt introduced the Indian Head $5 design in 1908. Unlike traditional raised coin designs, Pratt placed the principal design elements below the surrounding field. The resulting appearance remains one of the most distinctive achievements in American gold coinage.
The September 1 specimen realized $25,620. By comparison, Heritage sold a PCGS MS-64 example without CAC approval on July 16 for $16,470.
For a San Francisco issue that many collectors overlook, the result offers another reminder that exceptional preservation and surface quality can command significant attention.
David Lawrence Rare Coins: CAC Premiums Extend Beyond Expensive Rarities
Not every notable CAC transaction involved a five- or six-figure coin.
David Lawrence Rare Coins (DLRC) demonstrated that certification differences can influence prices across a much wider collecting spectrum.
On September 6, DLRC sold a 2024-P Liberty & Britannia silver medal, graded CACG Proof-70 Deep Cameo, for $160.
The medal has a compelling numismatic story. In 2024, the United States Mint and Britain’s Royal Mint united their chief engravers, Joseph Menna and Gordon Summers, to create a shared design celebrating the two nations.
Liberty and Britannia appear in opposing orientations, similar to the figures on a playing card. The design invites collectors to rotate the medal to appreciate both national symbols.
The U.S. Mint struck its one-ounce silver Proof medal in Philadelphia.
Two NGC Proof-70 Ultra Cameo examples sold through GreatCollections during September. One brought $104.61 on September 13, while another realized $111.22 on September 27.
Although the pieces shared top numerical Proof grades, the results reveal different levels of buyer demand.
Meanwhile, a 1921-D Mercury dime demonstrated that collectors also recognize quality in affordable, circulated rarities.
The Denver Mint struck only 1,080,000 Mercury dimes in 1921. A sharp postwar economic downturn had reduced the need for new circulating coins. Consequently, both the Philadelphia and Denver issues became important dates within Adolph A. Weinman’s celebrated dime series.
On September 27, DLRC sold a CACG VF-35 specimen for $750. Heritage had sold an NGC VF-35 example without CAC approval on September 1 for $488.
The premium highlights a central attraction of key-date collecting. Even coins with substantial circulation wear can command strong prices when collectors value their originality and overall appearance.
Another interesting comparison involved an 1876 Liberty Seated quarter, graded CACG MS-62.
The date carries special historical appeal. America celebrated its centennial in 1876, and the Philadelphia Mint struck more than 17.8 million quarters that year.
Unlike the rare 1864 quarter eagle, this issue owes its appeal largely to its classic design and preservation rather than a small original mintage.
On September 27, DLRC sold the CACG example for $625. A PCGS MS-62 specimen without CAC approval had realized $390.40 at Heritage on July 28.
Once again, collectors demonstrated that a coin need not carry a rare date to attract additional competition.
GreatCollections: Early Dollars and Classic Commemoratives Draw Strong Bids
GreatCollections closed September with several impressive results, including an early American silver dollar and two classic commemoratives.
On September 27, a 1799 Draped Bust silver dollar, graded PCGS XF-45 with CAC approval, realized $8,911.10.
The 1799 dollar occupies an especially important place in American numismatics. It belongs to the Heraldic Eagle series and represents one of the most accessible opportunities to own a genuine eighteenth-century United States silver dollar.
Although the Philadelphia Mint produced 423,515 dollars dated 1799, finding an attractive survivor with pleasing surfaces remains an important consideration for collectors.
The September result becomes particularly interesting alongside two earlier GreatCollections sales.
On August 9, a PCGS AU-50 example without CAC approval brought $7,715.40. Meanwhile, a non-CAC PCGS XF-45 specimen sold on July 19 for $4,132.70.
Thus, the CAC-approved XF-45 dollar commanded more than both the same-grade comparison and the numerically higher-graded AU-50 coin.
Of course, early dollars vary significantly in strike, surface quality, and appearance. Nevertheless, the comparison reinforces the importance of examining the actual coin rather than relying exclusively on its numerical grade.
GreatCollections also achieved an impressive result with a 1938-D Texas Centennial commemorative half dollar, graded PCGS MS-68 with CAC approval.
The Texas commemorative series celebrated the centennial of the state’s independence from Mexico. Sculptor Pompeo Coppini created an elaborate design featuring the Lone Star, an eagle, the Alamo, and prominent figures from Texas history.
The 1938-D issue belongs to the final year of the series and carries a tiny mintage of just 3,775 pieces.
The CAC-approved example, from the JFM57 Collection of Silver Commemoratives, ranks among the finest certified at PCGS. On September 27, it realized $17,875.
Earlier that month, on September 4, Heritage sold a PCGS MS-68 example without CAC approval for $8,845.
The difference was substantial, particularly for two coins sharing the same numerical grade.
Finally, GreatCollections offered a 1900 Lafayette commemorative silver dollar, graded PCGS MS-64 with CAC approval, that brought $5,060 on September 27.
Few classic commemoratives carry a more intriguing historical background.
The Lafayette dollar honored the Marquis de Lafayette and America’s enduring friendship with France. Its proceeds helped support a monument to Lafayette in Paris. It also became the first United States coin to portray George Washington.
The Mint struck the dollars on December 14, 1899, the centennial of Washington’s death, although the commemorative carries the date 1900 in its inscription.
Furthermore, the Lafayette dollar holds another distinction: It remains the only silver dollar issued during the classic American commemorative coin era.
GreatCollections had sold a PCGS MS-64 example without CAC approval on July 19 for $2,255.
The September CAC-approved coin brought more than twice that amount, providing another example of the strong demand for desirable classic commemorative silver.
What September’s CAC Coin Premiums Tell Collectors
The September results illustrate an important distinction in the rare coin market.
A numerical grade provides a starting point, not a complete description of a coin.
Two examples may share the same date, mintmark, and certified grade while displaying very different levels of eye appeal. Strike quality, luster, toning, surface originality, and the presence of distracting marks can all affect collector demand.
CAC approval adds another assessment of quality within an assigned grade, while CACG provides its own grading and encapsulation service.
Still, auction comparisons require perspective. Different coins, different bidders, changing market conditions, and the timing of each sale can influence prices. Furthermore, the absence of a CAC sticker does not necessarily mean that CAC examined and rejected a coin.
For that reason, these 12 examples do not establish a universal premium for CAC certification.
What they do reveal is the willingness of collectors to compete aggressively for certain CAC-approved and CACG-certified coins.
From a $160 modern silver medal to a $292,800 gold Stella, September’s auctions offered a revealing cross-section of that demand.
And for collectors studying the market, the lesson reaches beyond the holder: The grade matters, but the coin itself still makes the difference.
