If you collect coins, you've probably researched unusual ones that may still be in circulation. A rare coin marketplace lets aficionados buy and sell them, and you may make good money if you locate one in demand.
The 1967 Kennedy Half Dollar auction set a record at $6,995. The U.S. Mint intentionally omitted mint markings from 1965 to 1967 coins to reduce coin hoarding, making this uncommon coin notable. To honour deceased President John F. Kennedy, the Mint began striking these half-dollars in 1964.
1932-D Washington Quarter auction record: $143,750 The U.S. Mint released this George Washington bicentennial quarter. This design was famous worldwide until the Mint began the 50 state quarters series in 1999.
1943-S Jefferson Nickel auction record: $9,000 Wartime silver nickels from 1942 to 1945 include this one. Over 100 million Mint pieces were in circulation, and collectors saved many.
VDB Penny 1909 Auction record: $168,000 Its unusual story makes this Lincoln penny popular. Like many coin designers of the day, Victor David Brenner wrote his whole name in tiny letters. After Mint engraver Charles Barber changed the name to just VDB, newspaper writers noted that the designer was exploiting the coin for free promotion.
1C Double Die Reverse Penny 1983 Auction record: $7,050 No mint mark makes this uncommon coin collectible, and it sold for nearly $7,000 at an auction in 2017. The face of the coin lacks a mint mark, therefore it cannot reveal where it was manufactured.
No S Roosevelt Dime 1968 Auction record: $40,250 This rare coin sold for about $40,000 in 2008. This dime is unique because the Mint unintentionally struck the first proof coin without the S mint mark. The San Francisco Mint likely spotted the error early.
Die Buffalo Nickel Doubled 1916 Auction record: $281,750 Due to the double 1916 date error, collectors value this unusual coin. Whatever condition, it's worth thousands. The 1913–1938 series was designed by James Earle Fraser.
