I recently purchased a circulated 1871 Seated Lib. Dollar off of ebay,
I receive the item and drop it in the ol' dansco only to realize that
it has a "medal" orientation. The reverse has the same orientation as
the obverse, maybe rotated 5-10 o'clock relative to the obverse.
Do known examples of this exist? Any advice on how to authenticate
this coin short of slabbing?
