Growth and retirement
Forecasts are directional estimates, not guaranteed future prices or investment advice. Actual value depends on condition, demand, fees, and sale timing.
Limited to LEGO's in-store Monthly Mini Model Build program, the Literacy Day Unicorn (40403) is a small promotional release from 2020 whose short run and retirement created scarcity, and its novelty-driven appeal alongside lack of unique molds or licensed content has kept trading thin and appreciation modest.
