The Newcomb-12 is the only variety confirmed for Proof Braided Hair cents of this date, although most coins delivered from these dies are circulation strikes. Walter Breen listed just 10 different specimens of this Newcomb number in Proof with the comment that he had seen perhaps a "couple of dozen" more. Current research suggests this estimate to be high, with Rarity-6- having gained the most widespread acceptance in the modern market.

The example to the left was sold by Stack's Bowers Galleries in the November 2023 Showcase Auction, where it realized $10,200.
