Here is a bat that is MLB Authenticated from that date but AROD signed it as home run #639 and then John Taube and PSA/DNA put the same information in their LOA:

Am I missing something here or did AROD sign the wrong career home run and then PSA failed to research the bat properly to make a correction?
