Helping to calibrate ...
In the United States knowledgeable numismatists call these Cents ... as noted on the reverse of the coin.
There is indeed some lamination evident in your coin ... but honestly most of us ... myself included ... either save in a 2x2 for personal pleasure or throw them back in the junk bag.
There is IMHO no credible way short of
ebay shenanigans to add value to this coin ... a common error.
I turn them back in at the face value ... One Cent.
