The penultimate issue in the early Proof Buffalo nickel series, the Mint struck 1,050 examples of the 1915 for sale to contemporary collectors. The 1915 mirrors the 1914 as one of the best produced and most consistently attractive Proofs of the type. Where the two issues differ is in rarity, for the 1915 is scarcer in an absolute sense and considerably rarer in the highest grades. In fact, only the 1916 is rarer in terms of total number of coins known.

The example to the left was sold by Stack's Bowers Galleries in the Spring 2024 Showcase Auction, where it realized $2,880.
