Released early in the 2000s and since retired, Chromosomes Student Set (9743) drew buyers from education and STEM niches and has seen moderate post-retirement appreciation driven largely by scarce sealed examples, while limited display appeal and condition sensitivity keep broader market liquidity and demand constrained.
