Baseball Cards Price

How do I find the value of this baseball card?

I have an 'Upper Deck' 2000 Juan Gonzalez baseball card. It's number is "8 of 15"... I can't find it's worth. Can you help me? If it helps...It has a Pepsi logo on the front of it too.

1. google it
2. Because it has a Pepsi logo in it, I think it is a promo card of a set. So it is card 8 of a 15 card set and not serialed to 15 (meaning only 15 cards in existence). Which makes this card not particularly rare. Juan Gonzalez is not a popular player in terms of collecting but because it is a promo I estimate its worth between $0.25- $0.50.
