On the 1983 cent, I'm pretty sure the back has a bunch of gas bubbles, but on the front, above the R in LIBERTY, I'm not sure if that's a
Cud or a solitary bubble.
On the 2012D cent, the obverse and reverse both have a slight ridge following just along the rim. I'm not sure what caused this or if it is an error at all. Any information would be greatly appreciated!
And thanks in advance for any responses!
