Does Anybody Here Resell Video Games? - Need Advice

I want to get rid of all my ps2 games (over 300 games) problem is when I put them into the ps2 I get a disc read error on 99% of them. When I used them back in the day, they were fine but I guess now they don't work anymore which is strange.

Want to see the best way to get rid of them.

1. Should I bring them to my local game store as a trade-in?
2. Auction them on eBay as "as is"?

I would appreciate any advice.

Thanks!

If u can get them working sell the higher priced ones on ebay then trade in the rest. Search youtube how to clean them
