Dimes have been minted since 1796, but some are worth much more than ten cents.
The 1916-D Mercury Dime is a collector's gem due to its low mintage of just 264,000.
1942/1 Mercury Dimes from overpunched dies are highly sought after and valuable.
The 1874-CC Liberty Seated Dime is rare, especially with the 'Carson City' mintmark.
1894-S Barber Dimes are one of the rarest, with only 24 minted and 9 known to exist.
The 1796 Draped Bust Dime is a piece of history, being among the first dimes ever minted.
Condition matters: Uncirculated or 'mint state' dimes can be worth exponentially more.
Look for full bands on Mercury Dimes; sharp, horizontal band details increase value.
Always verify authenticity with a professional, as counterfeits of rare dimes do exist.
