I have boxes and boxes and more boxes and binders full of mostly hockey and baseball cards, dating from the mid- to late 80s.
I would say somewhere in the area of 100,000-150,000. My centerpiece is the 1986-1987 O-Pee-Chee hockey set that I have. I am lucky enough to have 4 Patrick Roy rookie cards, which are valued at around $1,000 each
.
I have a Bonds rookie, Kurri, Roenick, Lemieux second year. Basically I have just about any rookie in baseball and hockey from the 86 and 87 seasons.
