The LEGO Ideas series is a collection of sets that are made by fans, for fans. They’re created through a process that involves submitting a design, getting community support, and then getting produced by the wonderful folks at LEGO. The LEGO Ideas series has been around for a few years now and shows no signs of slowing down. Recently, one of the most popular sets in the series has been the LEGO Ideas Grand Piano, and it’s not hard to see why. It’s a fully-functional mini-piano that you can build yourself, complete with keys that actually work. I mean, come on, who wouldn’t want to impress their friends with their musical LEGO skills? The LEGO Grand Piano is just one example of the amazing sets you can find in the Ideas series. If you’re a fan of LEGO and creativity, I highly recommend checking it out. Who knows, maybe you’ll be inspired to submit your own design!

Theme Analysis

Because of its nature, the Ideas theme is very broad and in some respects it is hard to use the retired sets as a benchmark for future sets performance. That said, it is a very popular and successful theme which has delivered 12% annualised growth.

A couple of very successful sets are LEGO Ideas Voltron (21311) which has doubled its £160 RRP since retiring at the end of 2019 (annualised growth of 21%) and LEGO Ideas The Beatles Yellow Submarine (21306) which has nearly trebled from its RRP of £54.99 when it retired at the end of 2017 (21% annualised growth).

Set Number Set Name Retired Date RRP Current Value Total Growth Annualised Growth
21311 Voltron December 2019 £160 £320 100% 21%
21309 NASA Apollo Saturn V December 2019 £110 £141 28% 7%
21306 The Beatles Yellow Submarine December 2017 £55 £157 186% 21%
21308 Adventure Time December 2018 £45 £57 26% 5%

Comparable Set Analysis

As alluded to above, finding direct comparator sets is very hard within this theme, we have looked at some of the other Ideas sets that have no sub-theme and can see that there is a varied level of performance.

LEGO Ideas Maze (21305) has more than doubled in value since retiring in 2016 (13% annualised growth) and LEGO Ideas Birds has more than trebled in value since retiring in 205 (17% annualised growth).

Set Number Set Name Retired Date RRP Current Value Total Growth Annualised Growth
21322 Pirates of Barracuda Bay December 2021 £180 £250 39% 23%
21313 Ship in a Bottle December 2019 £70 £91 31% 8%
21305 Maze December 2016 £60 £134 123% 13%
21301 Birds December 2015 £40 £131 227% 17%


Whilst the LEGO Icons theme shows double digit growth across the retired sets, we don’t think there is a strong enough correlation between sets to use it as an indicator to recommend investing, especially at this price point and in the absence of any discounts.

That said we wouldn’t be against it as an investment, but we would probably wait to see whether there were any sizeable discounts available ahead of retirement.
