1846 Large Date

The 1846 half eagle entered production as the United States declared war on Mexico in May, and the federal mint at Philadelphia kept pressing gold on its usual rhythm while the conflict unfolded along the Rio Grande. Combined output across both date-punch varieties came to 395,942 coins, with the Large Date accounting for the larger share. Bullion still arrived from Appalachian mines and from foreign coin deposits; California gold was nearly two years from discovery, so the supply chain looked the same as it had for several years. When the date logotype changed mid-run, the result was two distinct varieties rather than a deliberate design revision. Coronet half eagles were in their seventh year of issue, and the dies showed familiar wear from steady commercial production.

Authentication starts with the basics. A genuine piece weighs 8.359 grams and measures 21.6 millimeters, struck in 90 percent gold with a reeded edge that should be unbroken and free of file marks at the rim. The Large Date variety is identified by the size and spacing of the numerals: the digits are taller and broader, the 1 and 8 sit close together, and the 6 carries a distinct rounded knob compared to the more compact, thinner figures on the Small Date. PCGS and Heritage cataloging entries note these date-punch differences as the primary attribution point, and a low-power loupe makes the call once a collector has seen reference images side by side. Of the two 1846 P varieties, Large Date is the more available and the version most often encountered in dealer inventory.

For a date-and-mint collector working through the Liberty Head fives, the 1846 Large Date is one of the friendlier 1840s Philadelphia issues. Circulated examples in VF and XF turn up regularly at modest premiums above bullion, and AU pieces remain affordable for a coin of this age. Mint State coins are conditionally scarce and command real money when they surface with original surfaces and clean fields. Cleaning is common on this date and suppresses value sharply, so eye appeal and surface integrity matter more than raw grade for many buyers. Background on production patterns, mintmark variations, and design history across the run appears on the Liberty Head Half Eagle series history.
