I'm not sure the name of this error but I'm so excited I had to share....there's like Something going on by the tree on the left side lol.....see what I mean???
It's a die break, specifically a "cud". The outer margin of the die broke off, leaving a raised blemish on the coin.
Nice find, cuds are a little harder to find in circ because something that large attracts the eye of even non coin collectors and they tend to hang onto it
Co to www.cudsoncoins.Com and see if its listed. If it's not contact bj Neff on that sight and put a link to this thread in the email. Of coarse I can just go look but it will be fun and educational for you to do the leg work
