Hello everyone, can you please tell me what error this penny has or is it from damage? Thank you for your time.
The bump near Abe's chin looks like a plating blister caused by zinc oxide under the plating. It is not considered an error, but just a defect. Planchets for the cent are not made at any of the US Mints.
The only time I even pay any attention to zinc pennies is when people post about them. It's the worst material the mint ever came up with. Nine out of 10 of them seem to have issues.
When you post a coin that you think is an error, it always helps to tell us what exactly you think is going on. Even if you don't use the correct terminology, point out where on the coin you think something is going on. From the replies you get, you can gain more knowledge in the area of error hunting. Happy hunting!
