1926-S

970,000 coins. The 1926-S Buffalo nickel has the lowest mintage of any regular-issue date in the entire series, and the tiny production combined with heavy circulation and notoriously weak strike characteristics makes the 1926-S a major key and one of the most challenging coins in the series to find in condition. For many specialists, the 1926-S is the hardest Buffalo nickel to acquire in Mint State regardless of budget.

Strike characteristics for 1926-S nickels are notoriously poor. San Francisco was producing the coins on worn dies with inadequate die maintenance, resulting in soft obverse portraiture, weak bison hair definition, and frequently blurred date digits. Even Mint State examples often show such significant strike weakness that specialists question whether the term "struck" even applies to the coins that came off those inadequate presses. Full-strike MS64 or better 1926-S nickels are exceptionally rare, and specialists pay substantial premiums for the few examples that meet strict strike criteria.

PCGS survival estimates place the 1926-S population at approximately 60,000 to 80,000 examples across all grades, with the vast majority in lower circulated condition. Very Fine and Extremely Fine examples are scarce. About Uncirculated pieces require active searching. Mint State examples are genuinely rare, and Gem-quality coins (MS65 and above) are among the rarest Buffalo nickels in high-grade collecting. The finest known is a PCGS MS65+ that has changed hands in private transactions valued in the low six-figure range.

The 1926-S is often paired with the 1918/7-D and the 1937-D 3 Legs in discussions of the most important Buffalo nickel key dates. Unlike those other two keys, the 1926-S is a regular-issue date (no variety or overdate involvement), which makes its extreme rarity in condition purely a function of mintage and strike quality. Heritage Auctions has sold Gem examples in the $25,000 to $100,000 range over the past decade, with exceptional strike coins bringing higher prices when they appear. For collectors building complete Buffalo nickel sets, the 1926-S represents one of the three or four most difficult acquisitions in the series.
