Pokémon lot 8+ lbs

I would like to first say that I know absolutely nothing about Pokémon cards. I simply sorted, according to the little date, bottom of the card. I learned about the star and diamond and circle, but I gave up on trying to sort those as well. There is approximately 2000+ cards in this lot. And according to the Internet, there are too many special ones for me to start sorting those. You will get everything you see in the pictures. Including the large promotional cards. When they’re all in the box, it weighs 8.7 pounds please do not ask me to pick out cards. I have no knowledge of what to look for, and I’m not going to do it. About 40 to 50% of the cards are sleeves. There are a few cards, under 50, that look like they were played with. Lastly, I have no idea how to price this… So please, if it seems unfair, send an offer.
