Hi, recently I came across a 2005 Kansas State Quarter that was in a collection that I inherited from my grandfather. He would go to the bank every time a new quarter was scheduled to come out and get some, so they don't have any wear on them - but this certain one has what I believe to be an error on it. On the back side of the quarter where the bison is, instead of "KANSAS" on the top it only says, "NSAS". I have been informed that this is known as "Grease Filled Die" Error, but what I would like to know is, what would something like this be valued at? I understand that the "In God We Rust" Error is fairly common in quarters, but what about something like this? Thank you so much!
