Most cards pre-2000s are pretty much worthless. I collected in the 90s and the only stuff that holds value are the rare inserts of big name players (Kobe, Jordan, Bird). Refractors, autographs, the occasional jersey card. The rest looked cool but are only gonna get you $5-$10 at best. My advice would be to hold onto a handful you like and give the rest away. Maybe you have some young kids in the family that might take a liking to them. If nothing else, Goodwill or post as a $0.99 lot on eBay.
