Baseball Cards Price

How much is the entire set of Mother's Cookies baseball cards worth?

I have Mother's Cookies promotional baseball trading card sets from 1987, 1988, 1989 and 1990. In my set is every single card, including many duplicates. Also, there are uncut promotional card sheets that have 8 trading cards of the same player on every sheet. I have several sheets with Nolan Ryan, Mike Piazza and Tim Salmon. Some of these sheets are in thick plastic frames and read R.O.Y PROMO SHEET on the back. I don't think that these sheets were for available to the general public so they are probably very rare. Everything is in mint condition and the 1990 sets are sealed in plastic. Can someone please offer me their professional opinion on the value of my collection? I would appreciate any advice - thank you!

1. Is there a chance that these are minor league cards, because Mike Piazza never played in a major league game until September 1, 1992? And since all your cards predate his major league debut by atleast two years, I am wondering how this can be.
2. Not as much as you think. Those sets were popular in the early '90 but the interest for those regional sets are not much in demand. If I was you, I would save it and give it to your kids/grandkids and tell them how much fun you have with it. Show them the true meaning of collecting baseball cards and then the interest of baseball. If you get lucky, your kids/grandkids might ends up in MLB one day and they will be forever gratefull Just my two cents!
