Hello guys ! I have this beautiful Morgan Dollar with a huge circular damage die on reverse. Does this damage add a value to this morgan ? In France we have a real market to error and damaged coin but I don't know fo US. Best regards from France
Nice find, mon amie! That's due to a cracked die. There are others that will be able to tell you more.
This site has alot of information. http://ec2-13-58-222-16.us-east-2.compute.amazonaws.com/wiki/Die_Crack Nice coin and photos.
So we differentiate between damage (which is generally what we say happens to a coin after it's been minted) and things like die cracks, which are flaws in the dies which make it onto the coin. Those we see as varieties or errors. Damage for us is a "bad word" but use some fancy terminology like die crack or strike through and you'll have us all drooling.
Die cracks aren't errors or varieties either, they are die stages, just something that happens to the die as it goes through it's life from new to worn out and retired. A die with a crack is the same die as it was before the crack just a person that loses a limb is still the same person (although maybe with a different attitude.)
Damaged COINS are bad, but damaged DIES are good. The OP asked about a coin struck from damaged dies.
