Original Sixteen to One MineAlleghany, CaliforniaFounded in 1896, the Sixteen To One Mine was named for the ration of the number of ounces of silver equal to one ounce of gold in the bi-metallic monetary system established by Portugal in 1698. Due to the unusual composition of gold from this mine—15% silver within 85% gold—the gold is extraordinarily brilliant in appearance, its color unparalleled.
