The 1867 Proof Shield Nickel comes with two reverses: the regular proof reverse and the pattern reverse, which is very rare. Extremely low mintage of 600 coins of which most were saved, making this issue scarce but very accessible. Scarce in all grades and becoming rare has a high-end gem. Hard to locate with cameo surfaces and a true rarity with a deep cameo, as only very few are graded as such.
