Lot of old sports cards offers 7 sleeves

Product Name: Lot of old sports cards offers 7 sleeves
7 sleeves of old baseball and basketball cards. There are some offers football and even a couple hockey cards mixed in that i have seen. Around 4/5 sleeves are baseball cards. I would say majority are Topps and anywhere from 1979-1989. There are other brands too. The basketball cards are little newer the ones I've checked are early 1990s. They are all in pretty good condition for their age. They were given to me years and years ago by my aunts boyfriend and sat in a Rubbermaid untouched for last 15 years. I have not gone through them as I do not know the value of sports cards. There are duplicates of some cards I'm sure. Other brands I've picked up were donarus and score. I would say there is conservatively 4000 cards. 600-700 a sleeve so there is probably more than 4000 cards that's just a safe minimum guess for me.
