Not sure if this is an error from the Mint or post mint damage. Coin is much thinner than a lincoln cent and in really bad shape as you can see.
Not sure. This cent is paper thin (about half the normal cent) like it is missing a layer and lighter than a cent.
That's because the missing portion has been taken away either by acid or some other form of corrosion. Thus, the appearance and the weight differential.
yup. In fact, I think it can be argued that its worth less than 1 cent in copper? you'd have to weigh it.
Many in circulation like that. You see in a chem class you take a cent, put it in H2SO4, allow to mostly dissolve, remove what's left so you don't loose any money. Now you take the left over solution from numerous such dippings, add more distilled water, filter through filter paper, place the final product in a beaker, place in cabinet with filter paper on top to allow for slow evaporation. If done properly you get a fantastic, dark blue, almost clear, crystaline structure of CuSO4.
