Ron Guth: The 1870 Three-Cent Nickel mimics the 1869, as both have similar mintages and nearly identical populations and grade distributions among the coins graded by PCGS. The most frequently-seen grade is MS-64, just slightly ahead of MS-63. The finest examples are fifteen at the MS66 level.
Clashmarks are less frequent on this date than they are on the 1869, but the strike is equally as nice. Collectors should attempt to find examples that show as many of the vertical lines as possible on the reverse.
