Is LEGO Sweet Mayhem a good investment?
Sweet Mayhem currently trades 541.2% above its $13 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 Sweet Mayhem so expensive?
Sweet Mayhem was released in 2019 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.
