Help! Weird Reverse of 2020 Shield Penny 0

[Zobel]

Hi I Just recently join NGC.  I know its not easy to find anyt ntriguing coin so my expectation maybe in a year's time i'll be lucky enough  to be sharing the first coin worth sharing here at the chat board.  But here I'm excited to find out more about this first coin I just picked up outside the casino.  It's a 2020 Shield Penny...I think the obverse looks normal but the Reverse I dont know what to make of it....see pic attached.  Any ireply and additional nfo will be very much appreciated.  Thank you in advance.

It looks like adhesive residue. It may have been removed from some marketing literature that tries to get your attention with an attached coin. These days, a penny is pretty cheap. Most such flyers have a nickel attached.

Soak it in acetone and I bet your cent will return to normal. As DWLange stated, it looks like it is just glue.
