1872 Shield Nickel. Doubled Die Obverse. Proof-67+ Cameo (NGC).A wonderful example of both the type and issue, this enchanting Superb Gem possesses awesome contrast between frosty devices and mirrored fields. Untoned on both sides with a razor sharp strike and virtually pristine surfaces. Although not recorded at the time by Mint personnel, the mintage of this issue was likely similar to that of most other early Proof Shield nickels. Bowers (2006) estimates it at 850 to 1,100 coins. Survivors are rare in the highest grades and, indeed, this beautiful Superb Gem is tied with just one other coin at PCGS as finest certified for the issue in the Cameo category. Struck from a doubled obverse die, evidence of which is most pronounced at the annulet at the base of the cross.
