Thanks for the list, but I'm afraid that I thought you were referring to much older cards. Cards from the late '80's and early '90's are, for the most part, quite common and of little value, even in mint condition. The baseball card companies over-produced in those years and even a complete set of 1989 Topps cards (792 in the set) can be purchased from a dealer today for $25-50.
Of those you listed, none are high value players (the best are LaRussa, Parrish and Honeycutt), but even their cards are worth in the $3-5 range in mind condition. The others are perhaps a buck or so each, assuming you can get someone to buy them. A dealer probably wouldn't even want them, and certainly wouldn't pay more than a quarter of the book value, if that, for the lot. You'd have to find a private buyer and even that wouldn't be easy.
To get some idea of the value of each card, go here:
Enter each card in the format shown (year, manufacturer, player's name) and it will give you an estimated value.
I'm sorry, but this group of cards will not make you rich!
