mistergee,
That price range is incorrect, it's $17 to $8500 and full bell lines are not applicable to proofs, only circulation strikes (it's assumed all proofs have full bell lines). In proofs there are two additional grade ranges ... cameo and deep cameo. A PCGS-graded PF70 DCAM coin sold for $8500. It all depends on the grade and w/o a photo, that's the best I can do.
