I have a 1990/91 Pro Set, Wayne Gretzky ( 2000th. point card )with the wrong back on it. It was found in a pack of cards in Niagara Falls at the time of the sets release. It has Roger Johansson of the Calgary Flames ( Card # 424 ) on the back. I have never seen another in my searching. I know this set was not a good set , but I am wondering if this is a good card and it's possible value.
The card has been in a thick protective plastic case since it was found.
