Liberty Eagle $10 gold coin (1883) (obverse) 1
Gold (Au) is a rare and attractive metal. Humans have valued it for millennia. Natural gold principally occurs as detrital grains and clasts in streams, rivers, or beaches (= placer deposits); and in hydrothermal veins, usually mixed with quartz.
Historic and current uses of gold include: jewelry, coins, electronics, dentistry, and government hoards.
The coin shown here is the obverse of an American ten dollar gold piece dated 1883. These are called "Liberty Eagles", in reference to the bust of Liberty on the front and an eagle on the back. Twenty dollar gold coins were called "double eagles".
The coin is 2.7 centimeters in diameter and about 90% gold.
