Why Collectors Paid More for CAC Coins in May
The number on the holder matters.
However, the coin inside the holder matters more.
That simple truth drove another strong month for CAC-approved and CACG-encapsulated coins in May 2026. Across Stack’s Bowers, GreatCollections, Heritage Auctions, David Lawrence Rare Coins, and other sales, bidders paid clear premiums for coins that carried the CAC brand.
These results do not tell collectors that every CAC coin will outperform every non-CAC coin. Markets never work that way. Still, the data tells a powerful story. In many direct comparisons, CAC-approved and CACG coins brought more money than similar certified coins without CAC approval.
In several cases, the spread looked dramatic.
Even better, one GreatCollections result gave collectors a near stopwatch comparison. Two non-CAC 1871 Liberty Seated dollars in PCGS XF-40 sold within seconds of a CACG XF-40 coin. The CACG coin brought $1,161.60. The two non-CAC coins brought $892.10 and $882.20.
That is the market speaking in real time.
Why CAC Still Moves the Market
Third-party grading changed numismatics. It gave collectors a common language. It also helped buyers trade coins sight-unseen with more confidence.
Yet experienced collectors know the next layer. Not all coins in the same grade look equal. Some coins lead the grade. Some sit in the middle. Others barely make it.
CAC built its reputation around that difference. The CAC sticker identifies coins that meet CAC’s standard for quality within the grade. Meanwhile, CACG holders bring that same concept into a full grading service.
As a result, bidders often treat CAC approval as more than a label. They treat it as a quality signal. In May 2026, that signal produced strong prices across many series, grades, and price levels.
Stack’s Bowers Results
1883 “No Cents” Liberty Head Nickel, Proof-64 CACG
On May 6, Stack’s Bowers sold a CACG-certified Proof-64 1883 “No Cents” Liberty Head nickel for $561.20.
Just eight days earlier, on April 28, Heritage sold a PCGS-certified Proof-64 1883 “No Cents” Liberty Head nickel without a CAC sticker for $402.60.
That gave the CACG coin a premium of about 39%.
1835 Capped Bust Dime, JR-1, XF-45 CACG
Also on May 6, Stack’s Bowers sold a CACG-graded XF-45 1835 Capped Bust dime for $463.60.
The coin represents the JR-1 die pairing, which specialists consider common. Even so, the CACG example outpaced a comparable non-CAC coin. On January 25, GreatCollections sold a PCGS XF-45 1835 dime without a CAC sticker for $369.60.
The CACG dime brought about 25% more.
1928 Buffalo Nickel, MS-65 PCGS CAC
On May 27, Stack’s Bowers sold a CAC-approved 1928 Buffalo nickel graded MS-65 by PCGS for $414.80.
Recent non-CAC examples fell well short. On May 10, GreatCollections sold a PCGS MS-65 1928 Buffalo nickel without a CAC sticker for $296. Earlier, on October 21, 2025, Heritage sold a different PCGS MS-65 1928 Buffalo nickel without a CAC sticker for $204.
The CAC-approved coin brought about 40% more than the May comparison. It also more than doubled the October 2025 Heritage result.
GreatCollections Results
1834 Classic Head “Plain 4” Half Eagle, AU-58 CACG
Gold collectors also paid up for CACG quality.
On May 3, GreatCollections sold a CACG-graded AU-58 1834 Classic Head “Plain 4” $5 gold coin for $4,265.50.
On April 19, GreatCollections sold an NGC AU-58 1834 Classic Head “Plain 4” half eagle without a CAC sticker for $2,860.
The CACG coin brought about 49% more.
1895-S Morgan Dollar, VG-10 CACG
The 1895-S Morgan dollar gave another useful comparison.
On May 10, GreatCollections sold a CACG VG-10 1895-S Morgan silver dollar for $688.60.
Three non-CAC VG-10 examples sold in the same month. Heritage sold a PCGS VG-10 1895-S Morgan without a CAC sticker for $488 on May 20. GreatCollections sold another PCGS VG-10 non-CAC example for $497.20 on May 24. Then, on May 27, Heritage sold a different PCGS VG-10 non-CAC coin for $512.40.
The CACG coin brought about 34% more than the strongest listed non-CAC comparison.
1871 Liberty Seated Dollar, XF-40 CACG
This result may be the most powerful example in the group.
On May 24, at 6:00:57 PM Pacific Time, GreatCollections sold a CACG XF-40 1871 Liberty Seated dollar for $1,161.60.
Six seconds earlier, GreatCollections sold a PCGS XF-40 1871 silver dollar without a CAC sticker for $892.10. Three seconds after that, at 6:00:54 PM, GreatCollections sold a different PCGS XF-40 1871 silver dollar without a CAC sticker for $882.20.
So, within seconds, bidders saw three coins of the same date and grade cross the block. The CACG coin led the group by about 30%.
That is a clean market test.
Heritage Auctions Results
1945 Walking Liberty Half Dollar, MS-67 PCGS CAC
On May 5, Heritage sold a CAC-approved 1945 Walking Liberty half dollar graded MS-67 by PCGS for $1,220.
This series gave a broader 2026 pattern. From January through May, CAC-approved MS-67 1945 half dollars sold from $862.40 to $1,708. GreatCollections recorded the $862.40 sale on May 3. Heritage recorded the $1,708 sale on January 27.
Meanwhile, PCGS MS-67 1945 half dollars without CAC stickers brought $610 at Heritage on February 3 and $660 at GreatCollections on May 17. NGC MS-67 examples without CAC stickers brought $524.70 at GreatCollections on January 25 and $524.60 at Heritage on May 26.
So far in 2026, and especially during May, CAC-approved MS-67 1945 half dollars have realized far more than the listed PCGS and NGC MS-67 coins without CAC stickers.
1935 Connecticut Commemorative Half Dollar, MS-66 CACG
On May 18, Heritage sold three certified MS-66 1935 Connecticut commemorative half dollars in successive lots.
The CACG coin brought $1,525. The PCGS coin brought $915. The NGC coin brought $860.10. Neither the PCGS MS-66 coin nor the NGC MS-66 coin had a CAC sticker.
The CACG example brought about 67% more than the PCGS coin. It also brought about 77% more than the NGC coin.
1946-S Washington Quarter, MS-67 PCGS CAC
On May 26, Heritage sold a CAC-approved 1946-S Washington quarter graded MS-67 by PCGS for $231.80.
Earlier in May, two non-CAC coins sold for much less. Heritage sold an NGC MS-67 1946-S quarter without a CAC sticker for $109 on May 12. It also sold a PCGS MS-67 1946-S quarter without a CAC sticker for $159 on May 5.
The CAC-approved quarter brought about 46% more than the PCGS non-CAC coin. It also brought more than double the NGC non-CAC result.
David Lawrence Rare Coins Result
1862 Three Cent Silver, MS-64 PCGS CAC
On May 3, David Lawrence Rare Coins sold a CAC-approved 1862 Three Cent Silver graded MS-64 for $1,100.
Comparable non-CAC coins sold lower. On May 12, Heritage sold a PCGS MS-64 1862 Three Cent Silver without a CAC sticker for $762.50. On March 16, Stack’s Bowers sold a different PCGS MS-64 1862 Three Cent Silver without a CAC sticker for $780.
The CAC-approved coin brought about 41% more than the higher of those two comparisons.
1858 Liberty Seated Half Dollar, MS-62 CACG
On May 3, DLRC sold a CACG-graded MS-62 1858 Liberty Seated half dollar for $1,650.
These coins do not appear at auction often in this grade. Still, two recent non-CAC results give useful context. On November 25, 2025, Heritage sold a PCGS MS-62 1858 half dollar without a CAC sticker for $960. On October 21, 2025, Heritage sold an NGC MS-62 1858 half dollar without a CAC sticker for $1,200.
The CACG coin brought 37.5% more than the higher comparison.
1883 Hawaii Quarter, XF-45 CACG
On May 3, DLRC sold a CACG XF-45 1883 Hawaii quarter for $280.
This result stands out because of the grade spread. On March 4, Heritage sold a PCGS XF-45 1883 Hawaii quarter without a CAC sticker for $149.
In the same sale, Heritage sold a PCGS AU-58 1883 Hawaii quarter without a CAC sticker for $237.90.
So, the CACG XF-45 coin brought more than the non-CAC AU-58 coin.
That is exactly why quality matters.
Other May Auction Results
1847 Liberty Seated Quarter, XF-45 CAC
On May 9, Gerry Fortin Rare Coins sold a CAC-approved XF-45 1847 Liberty Seated quarter for $976.
The gap against non-CAC coins looked large. On February 23, Heritage sold a PCGS XF-45 1847 quarter without a CAC sticker for $231.80. On September 3, 2025, Stack’s Bowers sold an NGC AU-55 1847 quarter without a CAC sticker for $384.
The CAC-approved XF-45 coin brought more than 2.5 times the NGC AU-55 result. It also brought more than four times the PCGS XF-45 result.
1866-S Liberty Seated Quarter, VF-20 CAC
On May 9, Gerry Fortin Rare Coins sold a CAC-approved VF-20 1866-S Liberty Seated quarter for $4,000.
On February 23, Heritage sold a PCGS VF-25 1866-S quarter without a CAC sticker for $1,708.
Again, the CAC-approved coin carried the lower numeric grade. Yet it brought about 134% more.
That result shows how strongly collectors can favor originality, eye appeal, and CAC approval over the number alone.
The Takeaway: CAC Adds Confidence
May 2026 gave collectors a clear message.
Bidders did not just chase grades. They chased confidence.
The strongest examples came from different series and price levels. They included Proof nickels, Capped Bust dimes, Buffalo nickels, Classic Head gold, Morgan dollars, Liberty Seated silver, commemoratives, Washington quarters, and Hawaiian coinage.
That breadth matters. It shows that CAC demand does not live in only one corner of the market.
Instead, collectors continue to pay for coins they trust. CAC approval helps identify those coins. CACG holders extend that same standard into grading.
For buyers, the lesson stays simple. Look past the number. Study the coin. Then weigh the market signal.
In May 2026, bidders did exactly that. They paid more for CAC.
