Movin On Estate Sales

These cards were in totes and mixed in with baseball cards. I separated them. There are many here in hard plastic protective cases. I don’t know a thing about them but guessing there are many valuable cards here. All from same estate as last two lots. There are hundreds of cards here! If I had to guess?? Easy 500; maybe 700? 
while separating I occasionally looked for dates. I saw 1991-94.
