Forecast Model

This shows the set's value since release and where our forecast expects it to go.
LEGO 21323 Grand Piano is an Ideas set released in 2020, containing 3,662 pieces. It builds a concert grand piano with a working keyboard, moving hammers and dampers, an opening lid and fallboard, and an adjustable bench. The model integrates with a dedicated LEGO app; the keys and internal mechanism interface with a smart device to play music electronically rather than producing acoustic sound. It is based on SleepyCow’s Playable LEGO Piano project from LEGO Ideas and was the first Ideas set marked 18+.

Our forecast puts Grand Piano at about $630 a year from now and $772 in five years, with its retirement expected in 2026.
Retirement risk. Grand Piano is expected to retire soon, by the end of 2026.
Collector and Investor Standing
LEGO Ideas speaks to adult collectors who like fan designed builds, and the Grand Piano gives them a playable model to admire. Fewer stores stocked it than most sets, which adds to its collector appeal. Investor interest looks strong too, with plenty of members owning or wanting it and activity picking up.
