So I have nearly 20,000 random sports cards. I'm looking to possibly sell them so I'm asking for somebody to give me a range on what I should ask for. I know there are a ton of variables in this, I'm not asking for an exact price, just around an estimate. I will say 3/4 of them are basic cards, not much special. I know that cards from the late 80's and early 90's were mass produced so there isn't much value there and a good bit of my cards are from that time. Anybody care to give me an estimate or anything? I know they aren't going to go for a ton of money, just thinking about what I should even ask for them. I'd appreciate any help.
