1802 2 Over 1

Every 1802 half eagle is an overdate. The Philadelphia Mint had carried an unused 1801-dated obverse die into the new year, and rather than discard a serviceable working die, the engravers simply punched a 2 directly over the original 1 and pressed it into service. No regular 1802 die was ever prepared, which makes this issue one of those rare circumstances where the variety is the type. The 53,176 figure recorded in Mint reports represents one of the larger early gold deliveries, and survival rates reflect that scale; the 1802/1 is meaningfully more available today than the 1799 or 1800 issues, and even outpaces the 1803/2 in the census. Robert Scot's Draped Bust obverse and the Heraldic Eagle reverse continued unchanged from the 1798 redesign, with the 8.75-gram, 91.67 percent fine planchets struck on a screw press at a facility still finding its rhythm with gold coinage.

Authentication starts at the date. Under 5x to 10x magnification, look for the curved lower loop or descending flag of the underlying 1 visible inside or trailing behind the 2. Die state varies considerably across the surviving population, and worn or weakly struck examples can obscure the underdigit, so a Bass-Dannreuther die-marriage attribution offers the most reliable path on borderline coins. Confirm 8.75-gram weight on a calibrated scale, verify the 25-millimeter diameter, and check the reeded edge for tampering or filing along the rim. Cast counterfeits typically fail on edge sharpness, weight tolerance, and the granular surface texture cast methods leave behind. Genuine examples show crisp dentil definition along both rims and consistent reeding depth around the full circumference.

For modern collectors, the 1802/1 functions as the practical type entry for the Draped Bust Heraldic Eagle subtype, with comparatively healthy availability across grades from VF through choice AU. Problem-free examples appear in auctions with reasonable regularity relative to the rarer dates in the series, and certified holders from the major grading services dominate the marketplace. Pricing tracks closely with the broader early gold market and tends to firm during periods of strong type-coin demand. See the full Draped Bust Half Eagle series history.
