Likely Mint-assisted. Still kinda neat. Owned by a friend in Panama. Not sure if one of the sets of dies is counterfeit. Also not sure if copper or zinc as I don't know the weight. I have a feeling the Lincoln is the genuine strike and the Panama strike was done after. No way these were struck simultaneously in my opinion. Sorry for the poor-quality photos. (Not taken by me.) I guess this is a foreign/domestic double denomination, dual off-center, chain strike? Authenticity definitely in question.
What if it was an off center Lincoln cent that a mint worker brought in to make an extra unique error? Or vise versa? No matter how it happened, still pretty cool.
Yep.. I saw the Cent over at Joe's Facebook page I'm not sure Check out this mess I acquired once 2 Different dates
I think this is a somewhat plausible error, although the human interference is just as suspect. The US mint was producing 1/10 balboa coins KM#10a from 1966 - 1982. http://worldcoingallery.com/countri...-1993) copper-nickel clad copper&query=Panama https://libertycoinservice.com/wp-c...s-checklist-foreign-coins-by-us-mint-type.pdf
The off-center strike on the Phillipines 50c coin looks like it was struck by two reverse dies, one with denticles and one without. In other words, a mule. Whether one or both of these dies were genuine is unclear. Many similar-looking errors turn out to have been struck by counterfeit or fantasy dies.
