U.S. 1880-O New Orleans Morgan Silver Dollar BU: The 1880-O Morgan had a production of 5,305,000. The vast majority were lost in U.S. government melts. Today just 12,000 of that issue may remain in mint-state condition. That's less than half of 1%, a remarkably low survival rate!
U.S. 1885-S San Francisco Morgan Silver Dollar BU: The 1885-S issue also has very limited availability in Uncirculated quality, with just 3% of the original 1.5 million mintage estimated to remain today. By contrast, up to three million of some earlier S-mint Morgans may currently survive.

Fewer than 2% of its eight million mintage are estimated to exist today in Brilliant Uncirculated quantity making this a tough find.
