1911-D

At 72,500 pieces, the 1911-D Indian Head Half Eagle holds the second-smallest mintage of the entire 1908 to 1929 run, behind only the 1909-O. The Denver Mint produced this date in a year when output across the gold series was uneven, and the 1911-D has stood out from the start as a date that demands attention. Survival estimates put roughly 2,000 to 3,500 pieces across all grades, and most of what comes to market is circulated, with About Uncirculated pieces forming the bulk of available supply. Mint State examples are a different proposition entirely, and the issue ranks among the most difficult dates in the series to acquire above MS-62.

Authentication starts with the basics: a genuine piece weighs 8.359 grams, measures 21.6 mm, and registers a specific gravity near 17.16 for the 90 percent gold alloy. Bela Lyon Pratt's incuse design should sit cleanly below the field surfaces with no added relief or tooling around the recessed devices. The D mintmark on the half eagle, unlike the famously soft D on the 1911-D quarter eagle, is typically well defined and fairly bold, with a relief similar to the 1908-D rather than the lighter 1910-D punch. Strike on the obverse is often soft on the headdress feathers, and the luster on this date is notably grainy, a die-preparation artifact that distinguishes it from earlier Denver issues. A PCGS or NGC holder remains the practical baseline for anything above modest money.

Auction results illustrate the steep price gradient by grade. Heritage moved an NGC AU-58 at $4,812 in a recent session, while a PCGS MS-65+ with CAC approval has crossed the block well into five figures, and the finest known examples reach into six. For most collectors building a date set, the realistic targets sit in the AU through MS-62 range, where the issue is obtainable with patience but always at a premium over the high-mintage Denver dates.
