Is LEGO Monorail Accessory Track a good investment?
Monorail Accessory Track currently trades 220.0% above its $97 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Monorail Accessory Track so expensive?
Monorail Accessory Track was released in 1988 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
