Here's the lowest-mintage O mint mark Morgan silver dollar! Only 300,000 Morgans were struck at the New Orleans Mint in 1893, and finding this coin in any grade today is indeed a challenge. Most of the 1893-O Morgans were released into circulation, so not many survive today to satisfy the large number of Morgan silver dollar collectors! Among "O" mint mark Morgans, the 1893-O silver dollar is without question the ultimate acquisition!
