Found a couple of things I would like to have some opinions on. You can not beat the lessons I'm learning on this forum. Thank you to all for the knowledge and help with my questions. First coin (Lincoln cent) I think has 2 different "Cud" marks. At least I think that is what I remember reading somewhere...just cant find that article again. Found this coin in a box of Pennies I searched today. I have a picture of each cud. Let me know what you think. The First cud is on the left of the E in United: The Second cud is a dot next to the C in Cent: The second coin (Lincoln cent) I believe is a Mint Mark over a Mint Mark. Let me know what you think.
the 1994 is not a doubled mint mark. they stopped hand punching the mintmark into the die in 1989. What you have there is zinc rot. the copper plating has split around the mintmark and the zinc beneath has started to rot. Richard
As for the first one, looks like probably plating bubbles. What year is it? A cud is a die break that involves the rim.
