Are there any places to go online to look up current values of baseball cards? I haven't had any luck finding one for a friend. The card is 93-94 Barry Bonds, and 1 of 5000. Any help is greatly appreciated, thanks.

Tough thing is, baseball card collector market has nearly completely fallen out over the last couple of years. Unless something is antique and truly rare/classic, it wont be worth much of anything now.
