San Francisco Mint employees contributed to Dime production in 1885, but only to a limited extent. The mintage of the 1885-S Dime was an anemic 43,690 coins. Most of the 1885-S Dimes entered circulation and few were saved by collectors, thus creating the rarest Dime of the 1875 to 1891 period. Even low-end circulated examples are highly prized. In Mint State, barely a dozen examples are known. Gems are extremely rare. The finest example is a single PCGS MS66 from the Eugene Gardner Collection, a coin which set a record price for the date of $49,937.50.
As might be expected, Dime researcher Gerry Fortin could identify only one die pair for this date.
