It's not every day that you see a 1979-80 O-Pee-Chee Wax Box. Come to think of it, I don't know that I've ever seen one. Although, it's not like I'm in the market for one of these. The auction is currently up to $1,500 but will probably sell for upwards of $2,000.
This is basically the hockey equivalent of 1986-87 Fleer Basketball. 1986-87 Fleer basketball contains Michael Jordan's rookie card. 1979-80 OPC Hockey contains Wayne Gretzky's rookie card. Both players are considered the greatest of all time in their respective sports.
Vintage wax like this is only going to get more valuable in the years to come. Stuff like this is very hard to find and the print numbers weren't near that of the modern products.
I think if I ever purchased a box this rare and valuable that I'd get it graded so I wouldn't be tempted to open it. Grading boxes and packs still seems kinda strange to me but it seems to be gaining in popularity as I see quite a few graded packs on eBay.
