Hello Jasper.. Welcome to CoinTalk. As mentioned it is damage. Someone altered it and/or it took a hit. We have seen a few over the years. Here is a thread I created about it. I call it the LIBERYY Cent Enigma! From 2018 https://www.cointalk.com/threads/the-liberyy-cent-enigma.309022/ Worth? 1 Cent
First, welcome to the neighborhood, Jasper! Using the CT "Search" function near the top right of each page, if you key in "LIBERYY", you will find that there are about three dozen threads that have been posted on this topic. ~ Chris
