Physical properties
Hardness: 2.5-3; Color: Reddish-orange metallic; Luster: Metallic; Crystal Structure: Isometric (refined to coin shape); Cleavage: None; Specific Gravity: 8.94
Formation & geological history
Produced through metallurgical smelting and refining of copper ores such as chalcopyrite. It is then minted into a 1 AVDP ounce round by private refineries (indicated by the '.999 Fine' marking).
Uses & applications
Investment bullion, collector's item, and store of value. Copper is also vital in electrical wiring, electronics, and plumbing industry.
Geological facts
Copper was the first metal to be worked by humans around 8,000 BCE. This specific round features the 'Walking Liberty' design or similar American eagle iconography popular in private bullion minting.
Field identification & locations
Identify by its reddish-orange color, metallic weight, and specific 'AVDP OUNCE' engravings. Found in coin shops and bullion dealerships rather than geological field sites.
