Morgan Dollars are a series of silver dollars that were minted in the United States from 1878 to 1904, and then again in 1921. Designed by George T. Morgan, these coins feature a depiction of Lady Liberty on the obverse and an eagle on the reverse. The coins contain 90% silver and 10% copper, making them highly sought after by collectors for their historical significance and silver content. Morgan Dollars are known for their intricate detail and have become iconic symbols of American numismatics.
