Growth and retirement
Forecasts are directional estimates, not guaranteed future prices or investment advice. Actual value depends on condition, demand, fees, and sale timing.
A small City scenery accessory pack from 2017, Build My City Accessory Set is in steady demand for layouts but lacks exclusive prints or minifigures, and recurring accessory refreshes mean its post-retirement appreciation has been modest and long-term upside is limited.
