Physical properties

Hardness: 2.5-3; Color: Silver-white (tarnishes to dull grey/black); Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 10.5

Formation & geological history

Formed in hydrothermal veins, volcanic deposits, and through the enrichment of silver-bearing minerals. The specimen shown was minted in 1909 from refined silver ore.

Uses & applications

Primary use in numismatics (currency), jewelry, electronics due to high conductivity, and specialized industrial plating.

Geological facts

This specific piece is a 1909 Barber Quarter. Silver is the most reflective element and the most thermally and electrically conductive metal.

Field identification & locations

Identify by weight (density), metallic luster, and lack of magnetism. Native silver is commonly found in the Keweenaw Peninsula (USA), Mexico, and Peru. Collectors look for well-defined strikes and lack of wear.
