As always I check my pocket change. Found two that caught my eye. Is this an error or just wear from something?
the cent has marks from a paper rolling crimping machine that puts cents into paper rolls and it is damage. not sure what is going on with that nickel ?
I agree with @spirityoda on the cent as far as the nickel it appears to have glue or some kind of lacquer. JMO Dave
The shadow on the nickel is about the size of a penny. Maybe another coin was resting on top of the nickel for a few years.
@Numiser is correct. Abe Lincoln was on top of Jefferson. It's a stain or discoloration caused by copper on the nickel combined with the conditions where the coins lay. Not a Mint error.
I'm curious if the nickel was submersed in water if the round shaped substance on it would come off over time. You can clearly see through that layer of gunk.
Thanks for all your replys, first time I have seen things like this on coins. Both caught my eye as not normal.
