But a type set mistake which would of course be ran until found and maybe corrected. It would be a more common error than a same on both sides or wrong denomination one of a kind or such.
So I don’t know if it should be called something else?
What do the coin numismatic society call this ? If done to a coin? Maybe they’d call it a f up and not an error not sure.
Good question for Mark Lighterman?
I think he’d be one to give it a good name for this kind of error.
Be kind of suiting to fallow a standard of norm and keep it similar to coin collecting terms.
In my opinion
Thanks
