1969 S 1c Struck Through Retained Rim Burr

Thanks Petespockets55- I don't see any indication this feature is affecting the obverse besides maybe some minor strike weakness in the rim around IN.

I think it's possible for this to be a defective planchet and a struck through rim burr. Like errorcoins222 said, burrs can occur to planchets/coins by multiple ways. I think we're use to seeing burrs caused by ejection contact with the collar but something else happened here, likely before it was fed into the press.

I'm not seeing how the alloy mix has anything to do with this error besides some slight color differences.

Thanks CoinHi.
I've added some arrows to your obverse image. The area of the rim above IN is where it looks like the metal has a "crease" from the metal being folded on itself.

IMHO, it doesn't look like just a scratch but it might be.

Thanks for taking a look Mike. I was close to describing this as a struck-in but wasn't sure it applied here.

Petespockets - The edge photo shows no evidence of this wrapping around to the obverse imo. Your arrows are pointing to what I see as minor strike weakness.
