Mintage: 50,000
Obverse Dies: 1 Known

The 1870 San Francisco date is very scarce in all grades and becomes rare in EF or better. In Mint State, the release of a small hoard allows some availability, though the date is still considered rare.

Plate Coin: Fortin 101, Well Struck, Bold Luster with Light Golden Toning

Expert Comments

Ron Guth

The 1870-S Dime is a semi-scarce issue, in sharp contrast to just about every other denomination issued in San Francisco in 1870 (for example, the 1870-S Half Dime and Three-Dollar Gold piece are unique and the 1870-S Silver dollar is exceedingly rare).  The San Francisco Mint produced 50,000 Dimes, virtually all of which entered circulation.  A small quantity was preserved by collectors such that perhaps 20-30 Mint State examples are known today.  Most of the known Mint State examples are well-preserved, usually in MS64 to MS65.  The best examples are MS66, but only several are known in that grade.

The strike on the 1870-S Dime is often soft in the centers, particularly on the N of ONE and the IM of DIME.
