1998-99 Topps Gold Label Checklist
This set is unusual in that each of the 100 cards in the base set have parallels, the rarity of which is determined by the style of the photo. Each base card is considered to be Class One, and parallels exist which are called Class Two and Class Three. There are then two forms of additional parallels of each of the Classes, and each of the parallels can be represented as another parallel. So in effect, for each player in the base set, there are 18 possible different variations. Whew!
