What the other members are telling you here is completely correct, and they are speaking with absolute certainty. That detail you are looking at under the microscope is a post-mint issue (damage or alteration that happened after the coin left the mint).
It is very common to find pieces like this. In fact, I also have a coin with a countermark and some dates that were manually stamped onto it long after it was minted. Many people tend to make these kinds of marks for special occasions, to commemorate something, or out of simple mischief, but it is not an official Mint error. Best regards and good luck with your hunts!
Thank you all very much
My wife and I just started getting into sorting and collecting coins
We’ve now gotten and gone through six boxes of the jfk rolls
In two of the boxes we had amazing luck and found 84 pre 70 coins

Does anyone have any information on the reverse of this coin
looks like a triangular punch
altered surfaces - possible acid
potentially was a no "FG" coin, but with the altered reverse we'll never know
Post mint damage.
No error there, just damage.
Collector, occasional seller
Poest mint damage
