1874 Liberty Seated Half Dollar. Arrows. Proof-62 (PCGS). There are only two Proof issues of the Arrows, Motto half dollar type -- the 1873 with a mintage of 500 pieces and the 1874, as offered here, with a mintage of 700 coins. The type as a whole is challenging, and survivors are eagerly sought at all grade levels by specimen type collectors. From the Abigail Collection, Part II.
