By adding two veteran stars, Kevin Garnett & Ray Allen, to a healthy Paul Pierce, the Celtics have seemingly transformed themselves into the team to beat in the East. While enroute to an 8-0 start this season, we witnessed KG's 95-96 Finest RC (his best base rookie) average $64.60 TAC through 11/17, with a high of $87.55 (on 11/17). Then came the team's first loss on 11/18. His Finest RC has dropped to an averge of around $51 since then. We need to keep in mind though, that for the past how many seasons, this card could be easily found for less than $20 TAC.
Ray Allen's best base rookie, his 96-97 Topps Chrome RC, has not experienced the same growth in value that KG's has. It's been a steady seller this season for around $10-15 TAC (before & after the Celtics' 11/18 loss). Since Allen has rookie-year autos (which KG doesn't), collectors seem to be going after those cards instead. Allen's two rookie-year autos are his 96-97 Skybox Autographics and Skybox Emerald Auto; both with BV of $60. Right before the season started, I saw one of his Emerald auto's sell for $24.04 TAC. I then saw one of his Autographics auto's sell for $116.49 on 11/13. That's quite an amazing jump (384%) for just a two-week period of time.Paul Pierce hasn't seen any significant changes in his rookie values (maybe because he wasn't a new addition to the team?). His 98-99 SP Authentic RC #'d 3500 has consistently sold in the mid $20's since the preseason. One card that should really garner some big bucks is his 98-99 Topps Auto (his only rookie-year auto), if you can find one. I've been keeping my eye out for one for the past couple of years, and haven't found any.
Barring any injuries, I believe that the Celtics will be able to overcome the reinvigorated red-hot Magic to finish the season #1 in the East. They may even have a chance to beat the Spurs or Suns, or whoever ends up winning the West. My hobby prediction is that KG will continue to benefit the most from this newly created super-team, with Allen & Pierce finally getting at least a little of the hobby attention that they've always deserved.
