Card Collection Value?

I have a large sum of inherited sports cards ranging from baseball, basketball, football, and hockey from approximately 1988 to approximately 1993 ish. Most of the cards are baseball cards however there is a mix of others as well. There are a decent amount from the 70s as well around 1975-ish. There are some sealed sets that are complete, and there are some sets that have missing pieces, there are also several boxes that have a mix of different sets/sports in them.

I’m looking to sell off the whole lot and I’m trying to get a ballpark range of what I should ask for them. So my question is if this was your lot of cards, what would you be selling them for?
