Morgan Dollars are a series of silver dollars minted by the United States from 1878 to 1904 and again in 1921. The 1879 Morgan Dollar, specifically minted in New Orleans, features the iconic designs of George T. Morgan, depicting Liberty on the obverse and an eagle on the reverse. Collectors value these coins for their historical significance, silver content, and varying mint marks, with the New Orleans mint mark "O" being particularly sought after. The coins are part of the broader collectible coin market, where condition, rarity, and provenance significantly affect their value.
