All known Proof 1870 Indian cents were struck from the same reverse die that the Mint used to produce restrikes of the famous Proof 1864 L on Ribbon (Snow-PR2). The estimated mintage for this issue is 1,000 coins, in keeping with the number of silver Proof sets prepared that year. Regarding the rarity of the Gem Cameo specimens, Rick Snow (2014) perhaps said it best: "Early die state pieces have cameo contrast and are very scarce. Original full red examples are also difficult to find. Many have subdued color and average eye appeal."

The example to the left was sold by Stack's Bowers Galleries in the Blue Moon Collection Part I, where it realized $4,935.
