Found this Kansas quarter, I looked it up and its one of the top 4 errors that everyone is looking for.
It's a grease filled die. "In God We Rust". I wouldn't put it in the top 4 errors that everyone is looking for. Interesting though. I've found 2 in my searches.
You can keep it as a neat thing to have if you don't have any more, but I personally wouldn't. I've seen better grease fills on coins that this and on better condition coins. This one is one that IMO is not worth the effort to keep it past it's novelty stage for someone.
Maybe it's in the "Top 4" errors for someone who doesn't know much about errors, but I wouldn't consider it in the "Top 100". Chris
That coin is so beat up I couldn't tell if that is a filled die or just some MD - guess all depends which picture you look at.
