Hello Jessie , what you have here is what's referred to as a parking lot coin. Sorry . Keep on trying . Happy Holidays !
This "affliction" is often called road rash, and there is no cure for it. No amount of treatment will make it go away.
Welcome aboard The CT Train. Hope you enjoy the ride and the many stops along the way. You will see this condition, many worse than your coin and as cpm9ball indicated, road rash is a condition which has no cure.
Welcome to CT, there will be better days and better coins ahead, keep your eyes open and keep searching! Good luck
Welcome @Jessie5, as already noted, it is just a damaged coin. The term is PMD, meaning Post Mint Damage. It happened after the coin left the mint and isn't considered a mint error. Looking at your previous posts, it seems your focus is on the U.S. cent. Have you done some research online to learn the minting process? It might be helpful to know exactly how the coins are minted so you can determine the likelihood of an error. Good luck on your hunt.
