Obverse Dies: 2 Known
Two sets of dies were used for 1869 San Francisco coinage. The reverse dies can be identified by a Small Thin S and and a Small Weak S mintmark. The Small Thin S is much more common than the Small Weak S.
Plate Coin: Fortin 102, Bold Strike and Luster With Faint Traces Of Gold Patina, Weak S Mintmark, Reverse of 1870-S and 1871-S
The 1869-S Dime is slightly scarcer than many of the other dates in the Legend Obverse type, but it is still readily available in most grades. Mint State examples tend to be low-end, and very few examples are known in MS65 or better. A single PCGS MS67 example exists which is one of the finest Dimes of the era. This date often comes weakly struck and the mintmark lacks definition. Many examples appear to have been struck from old, worn out dies.
According to Dime expert, Gerry Fortin, the entire mintage of this date is comprised of the output from only two die pairs. Either this is an amazing output per die or there are other die pairs waiting to be discovered.
