"Wrong-backs" were pretty common in the early 90's. As a printing error, it doesn't get listed on this site. This specific card could be quite rare or pretty common. There is no way to know. Some people consider it junk, while others would love to have this card. Not just collectors of those players, but some people specifically collect this type of mis-print.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
