This is 1938 Canadian penny , haven’t seen this error before in those pennies . I want to learn more about this coin , plz lemme knw if it’s worth keepin in .
I don't believe that is an error, and even though KGVIs aren't that valuable, I still see all of them as keepers because it is a retired design.
Don't assume that something that looks different is automatically some kind of mint error. There are all types of PMD - Post Mint Damage
