What is the price per piece for Mosasaurus?
At its $18 retail price across 26 pieces, Mosasaurus works out to about $0.692 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Mosasaurus a good investment?
Mosasaurus currently trades 540.1% above its $18 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 Mosasaurus so expensive?
Mosasaurus was released in 2001 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.
