Is LEGO Birthday Party Boy a good investment?
Birthday Party Boy currently trades 34.4% above its $5 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 Birthday Party Boy so expensive?
Birthday Party Boy was released in 2018 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.
