So your saying that is not an error? I can't find anymore on the internet!
How can it be an error? An error is usually one of a kind.
A different sized punch was used on that particular die so every coin
struck from that particular die would have that small MM.
The only other explanation is that one of them is counterfeit
but you didn't supply full size photos of both sides to determine that.
