1 if this is not a mule would it be a trail or a error coin ?
2 is this was milled or carved latter by a hobo this would make the coin lighter in weight as some metal would go in the process as this coin is heavyer and slightly larger this would make it a wrong planchet yes
3 so how could we explain the weight increase
4 so if this is heavyer and larger there must have been forgerys of this coin
1. It's not an error coin, it is an altered coin.
2. Was the 'normal'
Buffalo nickel you weighed in mint condition? If it was worn, as most are, that would explain the weight difference.
3. Same as above, the weight is probably normal.
4. There are no forgeries that I know of, but a nickel was worth quite a bit back then. I don't think it's a fake, it's just altered.
Your coin is not an error. It is physically impossible for that coin to be a mint error. It is a curiosity, and it is interesting. Still a nice find!
