Found this 1980 on the floor of a gas station today LOL... Pretty clean! The 87 has some weird looking stuff in the neck area and between LIBERTY and IN near the rim, it looks like letters may have been removed to me. Also it looks like there could be doubling in the ear lobe to the southwest..
Ear wax. Nothing to be concerned with. Take two aspirin and call the Doctor in the morning. All will be better then.
The 1987 has been damaged but the 1980 looks great for being found on the floor of a gas station. I think that's the difference between a zinc and a copper coin.
