Design
Large diameter 1821–27, reduced 1829–34. Close denticles, capped Liberty. Extremely low mintages across the board.
History
Among the toughest U.S. gold types. 1826 and 1834 last-year pieces are rare; most dates have mintages in the low thousands and high attrition from the 1834 melt when the gold content was reduced.
