Unfortunately, I haven't been able to find any examples of the Extreme inserts, but I have found planty of examples of what card 123 is - it's simply the base card. The Extreme Corps was a subset in the base set running from card 101 to card 129, not the same as the insert (partial parallel) set of similar name. This is the desciption of the Extreme insert set from Beckett:
"This 24-card set was randomly inserted in packs at a rate of 1:9; however, special cards like Power Zone and Warp Speed were inserted in packs at a rate of 1:18. The cards are borderless and standard sized. They carry color action shots that are up close and personal! The Topps logo can be found in either upper corner. The player's name is written in gold lettering at either bottom corner and is set in a firework-type display of colors. The player's team name is also written in gold and is also located in either bottom corner of the card. The backs have another action shot of the player along with a head shot. His career stats are listed as well as a short bio."
And their info about the base set:
"The 1995-96 Stadium Club basketball set was issued in two series of 180 and 181 standard-size cards, for a total of 361. Cards were distributed in 13-card regular packs at a suggested retail price of $2.50, and in 24-card jumbo packs. The packs were distributed in 24-piece boxes. Fronts are full-bleed full-color action player shots. The player's name appears in etched foil against an exploding star background and his team's name is printed in gold foil at the bottom. Backs feature a close-up head shot and a full-color action photo with a blue background. The player's name is printed at the top as is his biography, player profile and '94-95 statistics. A category statistic chart appears on the lower right side of the chart. Second series cards included these variations. The "Rookie Cards" as well as other subset cards were issued in basic hobby and retail packs with a silver prismatic foil. These cards were also issued one per special retail pack with a gold/orange-type foil background. Subsets include 10 cards of players from the two expansion teams (Vancouver Grizzlies and Toronto Raptors), 29 "Extreme Corps" and six "Trans-Action" cards. A parallel version of every subset card was inserted in rack and jumbo packs. The parallel versions of the subset cards feature silver and blue diffraction foil around the player's name and team name. These foil variations are priced at equal value."
Hope this helps.
