Hello everyone!

I still have a lot more questions as I am new to this whole thing. I saw this interesting mark on the back of this penny and was wondering if anyone knew what it could
Be/ what could have cause it. Thank you!

It doesn't look like a mark made during the minting process to me. Looks like something that happened after leaving the mint and is probably post-mint damage to the coin.

Looks to me like it is simply scratched.
