Each year, an exclusive behind-the-scenes event is held at the LEGO House in Billund, Denmark, the birthplace of the LEGO brick. The lucky few who secure a ticket to the annual LEGO Inside Tour are also gifted a rare LEGO set created specifically for that year's event.

Made up of 1,912 pieces and recreating past Inside Tour sets to mark the event's 20th anniversary, it's currently valued at $7,826 (£5.9k) with an average annual growth rate of over 35%. Used sets can sell for an equally spectacular $6,495 (£4.9k) on average.
