That's a good point, Doug, that shouldn't be overlooked.
Foreign planchet errors do occur, but you must be able to identify what planchet it was struck on.
In this case, you know that it was struck at the Philadelphia mint in 1952 and that it appears to be a primarily copper coin.
There are lists you can consult to see if any of that along with the size and weight correlates to a known foreign coin.
These are the only links I have handy:
