1915 Buffalo Nickel. Proof-67+ (PCGS). CAC.This is a truly delightful Superb Gem nickel whose desirability is enhanced by the rarity of its issue. Fully struck with intricate detail throughout the design, both sides also exhibit a smooth satin texture that is at the threshold of numismatic perfection. Lightly and attractively toned as well, this coin would please even the most discerning numismatist.The 1915 is the penultimate issue in the early Proof Buffalo nickel series. By the time of the issues production the Satin Proof nickel series had already proved to be unappealing to contemporary collectors who had grown accustomed to the Cameo and Brilliant Proof coins of the preceding Liberty Head type. Accordingly, yearly mintages for the Buffalo series fell off steadily from the series introduction in 1913 through the halt in Proof production in 1916. The 1915 was produced to the extent of just 1,050 Proofs, the second lowest mintage for the type after that of the 1916 (just 600 Proofs struck). Curiously, while survivors are scarce in an absolute sense, most are well preserved with strong technical quality and eye appeal. At least part of this is due to the great care with which Mint personnel produced and handled this issue. On the other hand, few 1915 nickels have been certified at or above the Proof-67+ level, confirming the condition rarity of this gorgeous specimen.
