At the official auction of the FUN Convention by Heritage in early January at the Tampa Convention Center, CAC approved coins brought substantial premiums over coins of same date, type and certified grade sold then or in the near past.
Here are ten examples among many that could be listed:
1. A CAC MS-66 1942/1 overdate Mercury dime brought $120,000. Two years earlier, the same auction firm sold a 1942/1 overdate with the same MS-66 grade, without a CAC sticker, for $76,375.
2. A CAC VF-30 1797 half dollar realized $96,000. In November 2016, another 1797 half dollar that was also graded VF-30, without a CAC sticker, was auctioned by Stacks-Bowers’s for $64,625. Earlier, in August 2016, Heritage auctioned still another certified VF-30 1797 half, though without a CAC sticker, for $58,892.18.
3. There were two MS-65 1911-D Indian Head $2½ gold coins in this FUN auction. The CAC approved coin brought $78,000, while the 1911-D without a CAC sticker realized $43,200.
4. A CAC MS-64 1930-S $10 gold coin brought $69,000. Other MS-64 1930-S Eagles auctioned by the same firm, though without CAC approval, brought $61,689.85 in January 2017 and $64,625 in January 2014 when market prices were higher at that time.
5. A CAC MS-61 1805 $2½ gold coin brought $33,600, 30.58% more than a non-CAC MS-61 1805 $2½ gold coin, without a sticker, sold by the same auction firm in July 2016, $23,325.
6. A CAC MS-66 1920 Walking Liberty half dollar brought $28,800. In October 2016, the same auction company sold another that received the same grade, but did not have a CAC sticker, for $16,450.
7. There were two MS-65 1921 half dollars in this FUN auction. The one with a CAC sticker realized $21,600 and the 1921 without a sticker realized $16,800.
8. There were MS-67 1933-S half dollars in both the January 2018 and January 2017 FUN auctions. In 2018, a CAC approved 1933-S brought $20,400. In 2017, a 1933-S without a CAC sticker, which was more colorful, brought $9,987.50, less than half as much.
9. In this FUN auction, there was a NGC graded MS-65 1906-D $20 gold coin with a CAC sticker and a PCGS graded MS-65 1906-D $20 gold coin without a sticker. The CAC-NGC coin realized $15,600, while the (no CAC sticker) PCGS coin realized $12,600.
10. A CAC approved MS-63 1875-S $20 gold coin brought $14,400 in this auction. In April 2017, the same auction firm sold an 1875-S that received the same MS-63 grade, though did not have a CAC sticker, for $10,575, 26.6% less.
