So, there's this guy that is trying to sell me this 1921 liberty coin, and send me this picture. What do you think? It's original?
Better pics but whatever is hiding beneath that crud may be hiding casting marks also. There are plenty of fakes of this coin around. I still would like you to pass on this. It's a key date and heaven forbid you get scammed. Better to wait until something nicer shows up. JMHO.
Unless you have the backing of ebay, I wouldn't touch it. Too many things make me think that the coin may not be a coin. Ask for pics of the edge.
