In 1862, the production of Dimes at the Philadelphia Mint dropped by more than half. Nonetheless, the 1862 Dime is considered a common date, and it is one of the most affordable dates of the type. Mint State examples are plentiful, even in Gem condition (for example, the PCGS CoinFacts Condition Census starts at MS66).
The 1862 Dime is known for frosty luster. Many examples show striated planchets from die polishing (not to be confused with hairlines). Fully struck examples exist and they are the ideal, but be prepared to accept some soft strikes if necessary.
Researcher Gerry Fortin has identified ten different die varieties of this year, of which two die pairs were used to strike Proofs.
