Good afternoon. I am new to coin collecting and have picked it up during this COVID mess. I have this penny I found in my change and it looks interesting on the reverse side. I was wondering if someone could help me understand what is going on and let me know if it is anything special. It is on a 1991 penny no mint mark. Any knowledge would be great, thanks.
the sliver of white you see is called "Split Plating". You have a clear, great example of it, but it's actually considered damage and isn't worth anything more. It is pretty cool to look at though. I'll find some websites .... the "no mint mark" is simply the Philadelphia mint .. they were the first mint and didn't need anything to identify their coins.

Thank you very much. The last time I posted a coin on here it became a crazy thread that was bashing on people that were bashing on me. Thank you for the knowledge, especially since I am new to this. The more knowledge the better.
The split plate doubling that @Clawcoins mentions is common on the Lincoln cents struck since 1982 when the US Mint changed the cent from 95% Copper to 97.5% Zinc.
There are more oddities related to Crappy Zincolns besides split plate doubling that do not add value to the Lincoln cents.
