Another potential error? I say potential because I'm still trying to learn the error's of my coins or my ways! I compared this one to some of my other 2008's (Alaska) and it could be. I think.
Very common on that design. It was covered here at CT (https://www.cointalk.com/threads/2008-alaska-6-clawed-bear-quarter.226678/) and many examples can be found. Might bring a small premium as eBay shows a few starting around $1. But "sold" ones are fewer to find.
