Limited to seasonal education channels, MASTERPIECE Challenge Set (45823) is a FIRST LEGO League Challenge release that now trades with mild post-retirement appreciation driven by scarce supply and low remake risk, and its niche audience and limited part crossover keep upside constrained and somewhat volatile.
