We have looked further within the Licensed sub-theme where there has been annualised growth of 16% historically and there some excellent performing sets including LEGO Ideas Wall-E (21303) which has increased in value more than 5-fold since retiring at the end of 2016 producing stunning annualised growth of 31% whilst LEGO Ideas The DeLorean Time Machine (21103) is now worth over 4 times its RRP (annualised growth of 19%).

This really is a slam dunk set for us. An iconic character in the Ideas theme and Licensed sub-theme both of which have excellent historic performance. We would happily recommend buying LEGO Sonic the Hedgehog – Green Hill Zone at RRP, but we are currently purchasing it at just over half of its RRP. Buy, and buy now!!!
