1821

The 1821 Capped Bust Gold $2.5 Quarter Eagle is the first year of the Capped Head Left sub-type and the issue that revived the denomination after a thirteen-year hiatus. No quarter eagles had been struck since 1808, when a gold-to-silver ratio favoring bullion over coinage made the denomination unprofitable to produce and pushed the Mint to set the dies aside. When production resumed in 1821, John Reich's modified design replaced the original Capped Bust Right with Liberty facing left, wearing a draped cloth cap, surrounded by thirteen stars and the date below. The reverse carries a perched heraldic eagle clutching arrows and an olive branch, with the motto E PLURIBUS UNUM on a ribbon above. Diameter was reduced to 18.5 millimeters, a noticeable change from the 1808 issue, and the recorded Philadelphia mintage came to 6,448 pieces.

For authentication, a genuine 1821 quarter eagle weighs 4.37 grams on a calibrated jeweler's scale and is composed of 0.9167 fine gold with the balance copper and silver. The diameter is the single most useful diagnostic on this issue, measuring 18.5 millimeters with a reeded edge and an up-down coin alignment. That figure separates the 1821 from the larger 1808 at roughly 22 millimeters and from the later Reduced Diameter sub-type of 1829 to 1834 at 18.2 millimeters, and it is the first thing a careful buyer should check with calipers. Cast counterfeits surface periodically and tend to show soft rim definition, pebbled fields where the original luster should sit, and seam evidence at the edge under magnification.

For modern collectors, the 1821 sits at the intersection of historical milestone and genuine scarcity. Survival estimates fall in the range of seventy-five to one hundred twenty-five examples across all grades, with circulated pieces in Very Fine to Extremely Fine appearing at major auctions a few times a year and About Uncirculated examples turning up less often. Mint State survivors are scarce and typically command strong premiums when they appear with original surfaces. Demand draws from type collectors seeking a single Capped Head Left quarter eagle and from date collectors building the short and challenging Capped Bust series.
