U.S. 1849 $10 Liberty Head, Very Fine: The year 1849 found the California Gold Rush in full swing. A great migration westward began that eventually led to the mining of gold equal to billions of today's dollars. In 1849, this $10 piece was the largest U.S. gold coin in commerce. Like other U.S. gold coins of the time, it featured the splendid Coronet Liberty engraving- the longest lasting gold coin design in U.S. Mint history. Today, it is estimated that as few as 1% of these lovely coins survive.
