1870 Liberty Seated Silver Dollar. OC-6. Rarity-2. MS-61 (PCGS).An olive-grey patina adorns much of this pleasing Mint State piece, save for an area of brilliant luster remaining at the central obverse. Scattered small abrasions become apparent under a glass through none of these distract the naked eye. The 1870 is the first silver dollar produced since the 1840s that saw appreciable domestic circulation at the time of issue. Many examples of this 415,000-piece circulation strikes delivery were certainly exported to the Orient, but enough remained within the United States that the issue numbers among the more frequently encountered of the Liberty Seated, Motto type in todays market. On the other hand, the 1870 is rarer in an absolute sense than the higher mintage 1871 and 1872, and it is particularly scarce in Mint State with as few as 150 examples remaining.
