The 1916-D Mercury Dime is a rare numismatic jewel. This centennial dime may be hiding in plain sight with only 264,000 manufactured. Collectors prize it for its rarity and historical relevance.
An extremely uncommon dime is the 1894-S Barber Dime. This dime is special to collectors since just 24 were produced. Scarcity and the historical background of its minting make it valuable.
Common coins might become valuable due to minting faults. Example: 1942 Overline Dime. The inadvertent overline on the coin's design makes it unique and worth $22 million to collectors.
The 1970-S Proof Roosevelt Dime shows that modern coins may be valuable. This proof coin is rare and expensive, with only a few made. At $22 million, it might be a hidden goldmine in regular transactions.
The Bicentennial Quarter, issued to celebrate the nation's 200th birthday, is collectible. However, a misalignment or double strike can make it a $22 million anomaly.
