Formation & geological history
Formed in hydrothermal veins and oxidation zones of ore deposits. This specimen was minted in 1882 during the Victorian era from silver extracted from Western US mines like the Comstock Lode.
Uses & applications
Historical currency, investment bullion, jewelry, and a major industrial material for electronics and photography.
Geological facts
Designed by George T. Morgan and minted from 1878 to 1904 (and again in 1921). It is one of the most collected silver coins in history and contains 0.77344 troy ounces of pure silver.
Field identification & locations
Identify by '1882' date, 'Liberty' profile, and reeded edges. Common in numismatic collections; rare in natural field settings. Check the reverse side for mint marks (O, S, or CC) to determine rarity.
