[Pricing] Pokemon card value (first edition, promo etc)

Good evening, I have had a series of Pokemon cards for years, there is everything, first editions, fossils, celebratory editions of the film, mew. mewtwo, practically they are all foil ... porygon promo and other things but I can't understand if and how much they are worth .. I made a gallery with everything, do you think they can be worth something?

Hard to give an estimate in this condition. Most of these look pretty rough. :/
