Ron Guth:
In 1861, the mintage of the Dime reached the highest level (1,883,000) since 1857. Because of this large mintage, the 1861 Dime is plentiful in virtually all grades, including high-end Mint State. Among Mint State grades, collectors are most likely to encounter an MS64, though even MS63 and MS65 examples appear almost as frequently. The PCGS CoinFacts Condition Census begins at MS65 and tops out at MS67.
The luster on this date is usually frosty, though lustrous examples are also seen. The strike is generally good, but fully-struck examples, with full detail in the wreath on the upper left reverse, are definitely scarce.
