1926-S Buffalo Nickel. AU-58 (PCGS). CAC.Lovely near-Mint quality for this key date Buffalo nickel. Dusted with olive-gold and light silver patina, both sides are well struck for a San Francisco Mint nickel from the 1920s with most design elements suitably bold in detail. Smooth, inviting and nearly in the Mint State category. At just 970,000 coins struck the 1926-S is the lowest mintage issue in the circulation strike Buffalo nickel series, survivors scarce to rare in all but the lowest grades.
