So a while back my uncle passed on a collection he had for a while, I guess he felt too old for them and gave them to me. Well was looking through them and came across these, and I am wondering if these are worth anything. Will anyone take these off my hands for a price?

Additional information: Dragonair is 1996, Dragonite is first movie edition, and Dragonair and Dark Dragonite are both holos.

I don't know much about Pokemon, and probably don't belong here.
tl;dr
I have these cards, what do?

(I had to resize the picture, so the cards may look like squares)
