Is there a free website where I can find the value of old baseball cards?

Answer 1

Completed sales at eBay.com.

Answer 2

Just put the player's name and the year of the card and the phrase 'baseball card' and a word like 'value' or 'collectible' into a Google search. If there is a match you will see it. There are many collectibles websites around. You may not get an exact match, as far as year goes, but there may be a card of the same player for a different year listed. That might give you a start to determine the value of a card.
