Ron Guth:
In 1884, as in the previous five years, only the Philadelphia Mint produced Dimes. The mintage dropped to 3,365,505 -- less than half that of 1883 -- yet the 1884 Dime is still a common coin. In Mint State, collectors are most likely to encounter an MS63 or an MS64, with slightly fewer pieces appearing in MS62 and MS65. Even Gems are relatively common, as evidenced by a PCGS CoinFacts Condition Census that consists entirely of MS67 examples with a pair of MS68's at the top end. The 1884 Dime usually comes well struck, with frosty to brilliant luster.
Dime researcher Gerry Fortin has identified 11 die pairs for this date. However, one of those pairs was used to strike only Proofs, which is in variance with preceding years, where Proof dies were sometimes used to strike coins for circulation.
