finding baseball/basketball card values?

[trout #2]

I just rediscovered a stash of baseball and basketball cards I acquired in the late '80s - early '90s. I didn't know much about collecting them when I got them, and have no idea now. Is there any easy way or authoritative guide to determine if I've got anything of value? It would be great to be able to fund some more knives.

becket pricing guides are the standard in sports cards. also be aware that to be truly valuable they must be graded and receive grades of 9.0-10.0, generally speaking. there are various grading services, the most respected are becket grading services and pro sports authenticators (psa) and usually charge per card.

condition, age, rookie cards, marquee players, complete sets, are just a few determining factors. pm me if you want additional assistance.
