Hi,
Can anyone tell me what type of error this is? what is it called? it is clearly marked with another coin.
Thanks
P.s. I can't get the other side, because of size which has error, too. Sorry.

It looks like it got struck with another cent already in the dies. I am not sure of the name, but similar to a brockage or is a brockage. In either case, as long as the reverse isn't messed up from it being pressed then I would say it is a legit error, but this is a commonly forged one.

Thanks for the answer, I was able to upload the other side of it. So that you may see both sides.

it looks like a vice job to me.... where someone took that coin and 2 others and squeezed them together with a vice... to make it look like an error.... in my opinion it is not an error but post mint damage.

I'm inclined to trust Matts opinion. He has seen many more errors than I have coins.

thanks for the information and help!!
