Someone collecting Lego sets could have earned almost three times as much as if they had invested in the stock market, new analysis has found.
Over the past 15 years the average return for someone invested in shares was around 4.1%, according to research carried out by The Telegraph.
By contrast, it found that Lego sets maintained in mint condition had jumped 12% a year over the same period.
Obviously not all sets have boomed in value, but those that are sought after can fetch massive sums from diehard fans.
Investing website BrickPicker.com cites the example of a Cafe Corner set, which initially retailed for about £89.99, but sold for a whopping £2,096 after it went out of production.
