One Victor Wembanyama rookie card. Sixty-three parallels. Every grade, every grader, tracked from first sale to today. 

Only on Slabnomics will you hear a ranking of all parallels by return percentage AND grader breakdowns.

I broke down the entire 2023 Panini Prizm #136 rainbow to find which colors and which grades actually paid, and the answers cut against what the hobby repeats. The famous Silver underperformed. A PSA 9 beat the PSA 10 in a lot of parallels. 

Listen in for which parallels had the best ROI; a full data teardown of a $138 million card market.
