Ron Guth:
The 1885 Liberty Head Nickel has the second lowest mintage of the entire series (after the 1912-S). Most of the Liberty Head Nickel dates have mintages over 10 million, some over 20 million, a few over 30 million, and two that are just shy of 40 million. As a result, the 1885 is a very scarce coin and a widely recognized, highly popular rarity. In terms of pricing, the 1885 generally costs more than the lower-mintage 1912-S, partly because fewer of the former were saved in the year of issue.
The PCGS Population Report shows MS64 as the most "common" Mint State grade. MS66 examples are very scarce and the inest example certified by PCGS is a single PCGS MS67.
