Forecasts are directional estimates, not guaranteed future prices or investment advice. Actual value depends on condition, demand, fees, and sale timing.
Limited to in-store promotional distribution, the Jet Fighter (40321) from 2019 is scarce by supply yet is a small monthly mini model without exclusive prints or minifigures, so collector demand and post-retirement gains have historically been mild and upside appears limited.
