Description
Struck in copper with a reeded edge, J-890 presents the three-star cap Liberty Head obverse and STANDARD wreath reverse in a metal that reveals different artistic qualities than the silver original. Copper's superior malleability under striking pressure often produces sharper hair detail and crisper star definition on the cap than silver strikings from the same dies, making copper patterns particularly useful for evaluating the quality of die engraving. The warm copper color lends a distinctly Mediterranean quality to the neoclassical Liberty portrait, evoking the ancient Roman bronze coins that inspired the Phrygian cap motif.
