Hi all I have this 2019 P nickel which on the reverse side down under the letters MER in America there is strange mark. Not sure what it could be?
Thanks there is something there I have never seen a cud other than a picture. Does a cud start there?
That dark spot appears to be a stain. Cud’s must touch the rim and be raised but this does not look like it’s raised.
Looks like a stain to me. Might try a Q-tip with some acetone on it to see if it lifts the stain or changes it in some way.
