1891

The 1891 Liberty Head half eagle came out of Philadelphia during a quiet stretch for gold coinage, with the main mint striking 61,360 business pieces alongside roughly 53 proofs intended for collectors and presentation sets. Output that year was modest by the standards of the long Coronet series, and the bulk of the production was paid out into commerce or held in bank reserves rather than saved by date. Workers used the Type 2 With Motto design that James B. Longacre had refined back in 1866, pairing Liberty's coronet portrait with a heraldic eagle carrying the IN GOD WE TRUST scroll on its breast. Each coin weighed 8.359 grams in the standard 90% gold and 10% copper alloy, and the planchets passed through hand-fed presses that left the rims and devices crisp on early strikes but progressively softer as the dies wore down through the run.

Authentication on an 1891 Philadelphia half eagle starts with the basics that defeat most casting attempts. A genuine piece falls within a tight range of 8.34 to 8.38 grams, and counterfeits made from base metal cores or low-fineness gold almost always miss that window when weighed on a jeweler's scale. The diameter should measure exactly 21.6 millimeters with no flat spots from a poorly fitted collar. Specialists also study the date numerals under magnification, since the 1 and 9 in this year were punched with crisp serifs that transferred sharply to the working dies, while transfer-die fakes show mushy or doubled outlines on those digits. The reverse motto ribbon and the eagle's neck feathers are good wear-test areas, since worn but authentic coins still hold sharp lettering at LIBERTY across the headband.

For modern collectors, the 1891 is a friendly date that opens the door to genuine 19th-century gold without the premiums attached to the famous low-mintage years. Circulated examples in Very Fine through About Uncirculated grades trade close to gold-content levels, making them popular as type coins or as the Philadelphia anchor in a year set. Mint State pieces become noticeably scarcer above MS62, and the jump to MS64 carries a real premium because few were set aside fresh from the dies. Proof strikings are a separate world, with the original 53-piece run leaving perhaps two dozen survivors today across all grades. Collectors building a deeper run should consult the Liberty Head Half Eagle series history.
