拍品描述： 1868 Shield Nickel. Proof-66 (NGC).An enchanting Gem, both sides exhibit bright, reflective surfaces that are free of all but the lightest champagne-gold iridescence. Fully struck, as expected for a Proof, and uncommonly well preserved for both the type and issue. The mintage of this early date in the Proof nickel five-cent series was not recorded by Mint personnel; Q. David Bowers (2006) estimates it at 750 to 1,000 coins.
