I have some questions about some of them. Is this one a 1996 Double D penny? Is this a 1989 Double D penny? What is this? It looks like a gas bubble but whatever it is, it is pre mint damage. Any help would be appretiated !! Thanks! -Tanner Stuart
First two are split plate doubling. Not true doubling, but a shift in the position of the copper plating during striking. No error or premium. The third is a gas bubble with the beginnings of zinc rot.
