Exactly how did this error occur at the press?
This should not matter that it is foreign, one peso, as my question is about the minting process. Did another blank get between the obverse die and the initial blank? That's the only way I could think this would happen, but I would love to learn other ways, if any. I have seen these type errors before, but never became interested until I saw this one.
