Hi this is for a friend of mine, he bought this flying eagle cent and cant figure out what the foreign coin planchet it was. I have no clue. any help is good help.
It wasn't struck on a foreign planchet, it was counter-stamped after it left the mint. I seem to recall that the mint tried to take the Flying Eagles out of circulation when the (copper nickel) Indian Heads came out in 1859. Maybe they were sold for scrap? And bought to convert into hacienda tokens or something similar, cheaper than having new ones struck. I have Almanzar's book, I'll try to figure it out. I'm going to stick my neck out and say this piece has at least the potential to be quite valuable, if a genuine counter-stamp.
Looks like honest contemporary wear on the reverse opposite the punched area? I'm with @doug444. Very cool piece. I'm not a counterstamp collector, but this one would've caught my eye.
It's an auction catalog, 50+ years old, that included a good many counterstamps and tokens. I didn't see any on Flying Eagles, but that doesn't mean anything. Email me when you are ready, and I'll consult with a guy at Stack's. I will need a really good scan, select a 2 x 2 scan area, 600dpi, midrange brightness enhanced one or two notches, both sides. No phone photos, please. If you want to consign it, he'll discuss terms; if it were my coin, I'd take the money and run, unless he says it's worth only $20. It is a very thin market for oddball stuff like this. My time, no charge, no percentage, you will negotiate with him directly.
