This coin is an exquisite example from the Colorado Gold series, minted in Philadelphia, and it holds a denomination of $10 (Ten Dollars), issued in the year 1861. Crafted from high-quality gold, this piece showcases the timeless beauty and craftsmanship associated with early American currency. Despite the numerical values for its dimensions, weight, and mintage being marked as '0', this coin's significance lies in its historical context rather than its physical specifications. It is a notable collectible and evokes an era of American coinage during the 19th century. The coin does not display a mint mark, suggesting it was produced in Philadelphia, the principal minting location at the time. Its design and finish are emblematic of the gold coins produced in the United States, representing both wealth and the rich history of gold mining in Colorado. This piece is categorized under the sub-type 'Coins' and further embodies the legacy of American numismatics, making it a must-have for collectors of historical coins or those particularly interested in the Gold Rush era. The absence of a specified designer should not undermine its appeal; this coin stands as a testament to American monetary history, celebrating the gold standard that underpinned the economy during its time.
