Rare First Gen. Pokemon Cards

Found my old binder with some cool first gen. pokemon cards, are these worth anything and does anyone still have there old cards?

Standard rare pokemon cards like Gyarados, Moltres, Zaptos, Articuno, Charizard all left in mint condition in this pokemon traders binder for roughly 11years.

 

I'm pretty sure my Grandparents still have mine. I'm sure they are worth some money. Look around on ebay or something. I hear my friends say they burnt theirs or just tossed them, and wished they kind of would haveheld on to them. Nice find.
