Physical properties

Hardness: 2.5–3 on Mohs scale; Color: Silver-white on fresh surfaces, tarnishing to gray/black; Luster: Metallic; Crystal Structure: Isometric/Cubic; Cleavage: None; Specific Gravity: 10.5

Formation & geological history

Formed through hydrothermal activity in ore veins or as secondary minerals in oxidation zones of silver deposits. Geological age varies by deposit location.

Uses & applications

Predominantly used in electronics, solar panels, jewelry, investment coinage, and industrial catalysts due to its high electrical and thermal conductivity.

Geological facts

The 1936 Washington Quarter shown is a 'specimen' of 90% silver and 10% copper. Historically, silver has been used as a currency standard for thousands of years.

Field identification & locations

Identify by high density, metallic luster, and malleability. Found in concentrated deposits in places like Mexico (as shown by the Mexican Peso coin), Peru, and China. Collectors look for specific mint marks and dates.
