Same coin is shown with two different grades in PCGS Coinfacts
The D.W. Klein Lesher Dollar is shown in XF45 and AU50. The pictures are different, but the coin is the same. I assume it was sent in for "reconsideration" or re-grading at some point, and upgraded one level.
The Population Report likely includes the coin as graded in both grades.
There is also a different Lesher Dollar that I know of where the owner removed it from the PCGS holder and sent the label back to PCGS a year ago. But it is still shown in Coinfacts and listed in the population report.
