1915-S

San Francisco struck 164,000 half eagles in 1915, a figure low enough to push this date into the semi-key tier of Bela Lyon Pratt's incuse series. The mintage matters, but what shapes the market is what came after. Most pieces went into circulation, took normal wear, and then faced the 1933 gold recall that pulled large quantities of pre-1933 gold back to the Mint for melting. The result today is a survivor pool that leans heavily toward Very Fine through About Uncirculated, with Mint State examples scarce in any grade and choice or gem coins genuinely rare.

Authentication deserves close attention before any purchase priced well above bullion. The 1915-S has long been a target for transfer-die counterfeits, and one of the most useful diagnostics involves the mintmark itself. Some struck fakes carry an S that was hand-carved into the counterfeit die, producing a shape and orientation that looks subtly wrong against genuine San Francisco mintmarks of the period. A real piece should also weigh 8.359 grams and measure 21.6 mm, with composition of 90% gold and 10% copper. Because the design is incuse, with devices recessed below the field, an added or altered mintmark is harder to disguise than on raised-relief coinage; the surrounding metal sits at the same plane as the rim and reveals tooling under magnification. For any coin offered above the common-date level, certification by PCGS or NGC is the safest route.

Surface originality drives premiums on this date. Many examples have been cleaned or dipped over the past century, leaving a flat, washed-out look that contrasts with the warm orange-gold tone collectors prize on undisturbed pieces. Stack's Bowers offered a PCGS AU-50 example in a recent Baltimore sale that drew strong interest, a reminder that even circulated coins find ready buyers when the surfaces are honest. The 1915-S marks the last San Francisco half eagle struck before a long production gap, giving the date added significance for type and date collectors alike.
