By the mid-1990s, most sets boasted insert sets. It is still a staple of cards being made today. In 1996, nobody embraced the insert set more than Fleer Ultra. I'm pretty sure that they advertised that there was an insert card in every pack. They way to do this was to have lots of insert sets. In 1996, Ultra had 17 different inserts, each having 10-20 cards and each having a gold parallel version. I'm including in this count the ultimate insert set, a parallel of the base set itself, which had 600 cards. I've got 11 of them, including one of the gold parallels.
