well I found this:
The 1895
Morgan dollar:
The 1895
Morgan dollar is known as the "King of the
Morgan dollars" because it is the rarest and most valuable of the entire
Morgan dollar series. PF-68 specimens of this rare coin have sold for upwards of $120,000 at auction.
According to U.S. Mint records, there were 12,000 regular circulation
Morgan dollars struck for 1895, and 880 Proof specimens struck. However, only 75 to 80 of the 1895 Morgans have been accounted for, all of them Proofs. Where did 12,000 plus coins go?
A Mysterious Disappearance?:
Numismatic scholars are divided in their opinions as to why the 12,000 business strike specimens of the 1895
Morgan silver dollar have vanished into history. Most believe that the coins were never minted in the first place, and that this notation in the Mint accounting ledgers is in error. Some believe that the coins were minted, but melted down for various reasons. I even read one theory that proposes the coins were lost at sea in a shipwreck.
