Collectible coins encompass various categories, including historical, rare, and commemorative pieces, often sought after by numismatists and investors. The G 10 refers to a specific gold coin denomination, typically associated with the value of ten dollars. The Dubosq Company was active in the mid-19th century, particularly around 1850, in San Francisco, which was a hub for minting and trading coins during the California Gold Rush era. Coins from this period are valued for their historical significance and rarity.
