What is the price per piece for Underwater Robot?
At its $20 retail price across 207 pieces, Underwater Robot works out to about $0.097 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Underwater Robot a good investment?
Underwater Robot currently trades 91.2% above its $20 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 Underwater Robot so expensive?
Underwater Robot was released in 1999 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.
