Collectible coins, particularly those from the United States, can vary widely in type and historical significance. The G 20, often associated with the U.S. Assay Office of Moffat & Humbert, refers to gold coins minted during the California Gold Rush era around 1852. These coins were intended to facilitate trade in a time of economic upheaval and represent a unique fusion of artistry and commerce. The Moffat & Humbert facility was instrumental in refining gold and producing coins, contributing to the establishment of a stable currency in the rapidly growing Californian economy.
