The Topps Rookies Commemorative sets (or Topps Glossy Rookies) were only released for five years between 1987-1991. Like the Topps All-Star Game Commemorative sets (or Topps Glossy All-Stars), these cards were represented by the year prior to their release. The Glossy Rookies could be found in Topps Jumbo Packs containing 101 cards each.
Like the Glossy All-Stars, that could be found in Topps Rack Packs containing 49 cards each, I didn't collect any of these Glossy Rookies in 1987. Why? Well, for one, I could barely afford the 40 cents it cost to purchase a 17-card wax pack as a 10-year old in 1987. There's no way that I was going to be buying 101-card jumbo packs. It never even crossed my mind.
Looking back, it sure would've taken quite a number of Jumbo packs (22 if you're lucky) to complete one of these Glossy Rookies sets. That's 2200 Topps base cards and 22 Glossy Rookies cards, which is almost enough base cards to complete the 1987 Topps set three times over, if once again, you're very lucky.
This understanding now brings me to the conclusion that Topps Glossy Rookies sets should be selling for a whole lot more than the current market demands--but they're not. A set like this might cost you $6 right now online.
The Topps Glossy Rookies sets mirrored the size of the Glossy All-Stars' 22 cards for the first 3 years of their production between 1987-1989. In 1990 and 1991, the Glossy Rookies sets would increase in size to 33 cards. That's a whole lot of jumbo packs.
The key cards in this set seem to be the Rafael Palmeiro and Will Clark. Other notables include Wally Joyner, Ruben Sierra, and Jose Canseco.
Currently, I have my Topps Rookies Commemorative insert set placed into my '87T binder at the very back (after the 60-card Glossy Send-ins set and the 22-card Glossy All-Stars set).
