What are the prices of these cards?

I recently got over 10k baseball and baseball cards. Someone was going to throw them away so I asked him to give them to me. I been searching for the price of a lot of them and most of them don't cost more than $1.00. I searched for Joe Dumars cards and they only cost 1 buck. Not worth it the hle. It least with ebay's fees and shipping I will get probably less than .50c per card and that's if I get to even sell them. Many of the same cards I have are for sale on ebay so there's a lot of competition out there. Also if I want to post more than 50 bids of .99c a month then I will have to make a store with them which cost $16.00. I think I am just going to keep my cards in my basement and wait a few decades to see if they value something later on. If not then I will give them to my grandchildren or try making a craft with them idk xD Good Luck!
