I have a baseball card of nolan ryan as a baby how much is it worth.

I have never heard of a card like that but Im not a collector either. Also it will depend if its graded etc and authenticated.

Here is a link to a discussion over at eBay and the value of his cards. Seems it can go either way and yours sounds like a novelty card of some kind.
