So check this out. Here we have a 1943-S steel cent. Something happened along the way and we end up with this kooky design all over the obverse.
The design almost looked a little like this one: https://www.ngccoin.com/news/articl...kYkRNOWJaSHJcL2FYamtlSVwvK2grMHg2bXpmUGs9In0=
I couldn't think of anything with a diamond pattern like that, but a vice would definitely do the trick.
Interesting. You coin does appear to have the same marks. So that 1964 sent was not only made on a foreign coin, but also on a cancelled foreign coin? Weird. The article says that it's likely not an intentional error because it was found in circulation. They're presupposing that this story is true though. If the original owners got it some other unfair way, of course they'd lie about the story so they could strike it rich. However, I guess it is possible that the planchet producer could have had a worker that threw it in as a joke and it then found it's way in circulation. If your coin, or the one I've seen, has those marks, does that mean it was supposed to be cancelled. I've seen those waffle cancelled coins in slabs (that are unappealing IMO), but didn't know they used to cancel with little triangles
I broke my eyes going over the thing with a 20x loupe but was unable to find any evidence of it being an overstrike on an indian coin. Bummer.
