This is my wheel house, especially the early 90s. Compared to baseball and basketball for this era, hockey graded single populations are relatively low in a 10s. Upper Deck boxes for 90-91 and 91-92 are inexpensive and loaded with rookie cards in the high and low series. OPC Premier boxes are much more expensive but have the best ROI for the rookie class. Jagr rookies from OPC Premier are the king, selling anywhere from $200-700. The Upper Deck values are much lower, but still a solid card at a 10.
Other 90-91 OPC/Upper Deck rookies with value @ 10: Modano, Fedorov, Mogilny, Joseph, Holik, Bonda, Richter, Roenick, Sundin, Recci, Belfour (not in OPC), Domi (not in UD), Niedermeyer (not in UD)
90-91 Score is very cheap but has Brodeur's only rookie. Jagr, Modano, and Lindros are in this too. Boxes of this are about $10 each, but it's very hard to get a 10 on the singles since they're often off center and have chipping on the red borders.
91-92 Upper Deck rookies with solid 10 prices are Selanne, Forsberg, Hasek, Tkachuk, Khaibibulin, Palfy, Weight, Amonte, Yashin, LeClair, Lidstrom (Canada Cup & Young Guns).
92-93 Upper Deck is mostly trash except for the high series with Pronger, Kariya, Samsonov, Marchant, and Koivu. There's also a high series Selanne Young Guns, but it's not a rookie.
I'm sure I missed some details so someone feel free to correct me.
