1912-S

The 1912-S Indian Head Half Eagle came out of San Francisco at 392,000 pieces, a combined total that covers two distinct catalog entries. This page handles the standard issue, the one with a clearly defined S mintmark above the arrow shafts on the reverse. A separate listing covers the Weak S variety, where die filling reduced the mintmark to a faint blob or wiped it out entirely. The split matters more than collectors of the date often realize: the San Francisco mint had serious die problems through the 1912 production run, so the well-struck Strong S is actually the harder coin to find, while the muddied Weak S has become the default look for the issue.

Authenticating a Strong S starts at the mintmark itself. The serif and overall shape of the S should read cleanly under a loupe, with the upper and lower curves distinct rather than fused into a soft lump. Compare against a known Weak S example and the difference is unmistakable. From there the incuse design verification applies: the headdress feathers, cheekbone, and recessed Indian portrait should sit below the field plane, with the rims and field intact rather than the design being raised. Specifications should hit 8.359 grams and 21.6 millimeters, with a specific gravity near 17.16 reflecting the 90 percent gold composition. Strike quality on this date tends to run softer than the 1908-S or 1909-S even when the mintmark is sharp, so a Strong S with crisp central detail commands a real premium over one that is technically Strong S but otherwise mushy.

For collectors the date is a classic condition rarity. About Uncirculated examples surface with some regularity, lower Mint State grades require patience, and anything above MS-63 is a serious find for the series. A PCGS MS-62 with CAC approval that crossed the block at APMEX recently sits in the typical range where most Strong S buyers operate, and the price climbs steeply for properly struck pieces certified at MS-63 or finer. Most collectors pursuing a complete date set will accept the standard 1912-S in the AU range and add a Weak S example separately to round out the variety story.
