A portion of the reverse rim from about the E in STATES to the E in AMERICA is missing. The rest of the reverse has a small rim. Is this an 'error' of any significance? or just a common strike error? I looked on www.Error-Ref.com but didn't see it mentioned unless I'm looking in the wrong location.
It would help to see the entire coin in one photo, but I'd say it's caused by a misaligned die strike.
