This is my first post, I have a question regarding a possible error or maybe post mint damage on the obverse of my coin. Like the title says, it’s a 2003 D - Illinois I found roll hunting and I can’t find anything specific on the anomaly. Some sources said possible heat damage, but I don’t see any charring or stark discoloration. Other sources said it could be contaminants on/in the metal during minting. I’ve attached 3 photos of my coin, any help and information would be greatly appreciated!
