Old rare pokemon cards, are they worth anything?

I have a binder of about 1,000 just rare and holographic pokemon cards. Theyre about 10 years old, theyre nothing but the first three series. 1rst series, forest, and fossil. I have every single rare card, and almost all them are holographic. I even have multiples of Charizard, Blaistoise, Venasaur, 4 anchient Mews and a lot of 1st editions. Theyre all practically mint besides a few. I also have some Japanese ones, and a lot of the first series with the new pokemon (I dont remember what its called) But I have a lot of the rare one. ex: Rockets Mewtwo, Herarcross, Typhlosion, Meagnesium, and Feraligator. I apologize if I spelt them wrong, it's been a while. I was wondering if anyone would buy these if they saw it on Ebay or something. I'd look on ebay myself but no one is selling a collection like this. I was thinking try and sell them or hold onto them for a long time and maybe theyll be worth something. What do you think??
