The main reason I collect One Cent error coins is this...
If I collect every single type of known common error
Lincoln Cent, Even if the collection goes into hundreds of coins, if I decide to keep every single coin, regardless of the degree or type of error, I will still only have an investment of a few dollars. So I keep all of the errors I find. My goal, ?
Maybe to make a display of the degrees of various errors.
Either way you go, it's cheap searching for One Cent examples.
If you decide it's no longer interesting, spend them.
