Arguably the best player to ever play the game. Some love him some don't. However his stats speak for themselves. So many related collectibles you could never discuss them all. The most popular might be his rookie card. As a gas fitter i remember working at a house putting a heat run in the sons bedroom in the basement. I look over at one of the walls and low and behold there is a OPC Gretzky rookie card pined to the wall with five thumb tacks. I couldn't believe it. This was in the early 90s. I said to the kids dad do you know how much that card could have been worth? "Is that right" he said.
The closest i have got to the rookie is the 1992 O-PEE-CHEE anniversary series card below.
I remember in the 80s, i used to have a friend who loved Gretzky. It,s all he talked about. So another friend and i thought we would buy him a doll at the local Stedmans store. It was made by Mattel and was only around ten bucks or so. I guess he got the last laugh, as he still has it with the original box.
I've seen them go from 50 to over a hundred bucks on Ebay.
