The 1903-O was once the "king of Morgans", with a rarity exceeding even the 1893-S. With an original mintage of just over 4.5 million very few were distributed because they weren't needed in commcerce. Many were melted after the passage of the Pittman act in 1918. Until roughly 1962 as few as 10 specimens were known to exist. In 1962 coins that were originally stored at the Philadelphia mint began to surface, which caused a numismatic gold rush. Still a tough date this coin is a great specimen. Subtle rim toning and strong strike. CAC green bean for strength of grade. Very strong for a 64.
