1822

The 1822 Capped Head Half Eagle is widely regarded as the rarest regular-issue United States gold coin. Philadelphia struck 17,796 pieces that year, and only three are known to survive today. Two of the three live permanently at the Smithsonian Institution: one came through the Mint Cabinet by way of the Louis E. Eliasberg Sr. holdings, and the second is a Mint Cabinet piece off the market since the nineteenth century. A single example remains in private hands. Most of the mintage was paid out to banks for international settlement, and at the prevailing gold-to-silver ratio, a half eagle of 0.9167 fine gold was worth more as bullion than as money. Refiners and exporters melted the coins by the bag through the late 1820s and 1830s.

With only three coins known and two locked into a public collection forever, no living buyer will ever acquire an unverified 1822 half eagle. Each surviving specimen is named, photographed, and pedigreed through the published record. The single privately held coin is universally referred to as the Pogue specimen, after its long stay in the D. Brent Pogue Collection. Authentication for this date is therefore a question of provenance, not of die markers in the usual sense. Any institution working with the coin reconciles the piece against published photographs, weight, and physical description, then traces the chain of ownership through cataloged sales. Standard specifications are 8.75 grams, roughly 25.0 millimeters, 0.9167 fine gold, and a reeded edge. Bass-Dannreuther catalogs the year as BD-1, the only die marriage produced.

The Pogue specimen set the modern auction benchmark when Stack's Bowers sold it in March 2021 for $8,400,000, the highest price ever realized for any half eagle and one of the highest results for any United States coin. That sale fixed the 1822 in the small group of trophy issues that define the upper tier of American rarity, alongside the 1804 silver dollar, the 1913 Liberty Head nickel, and the 1933 double eagle. For the wider series, the 1822 sets the ceiling every other date is measured against, and it is the coin most often cited when collectors discuss why early Capped Head gold survived in such small numbers.
