Is LEGO The Swamp Adventure retired?
Yes — The Swamp Adventure (21240-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.

What is the price per piece for The Swamp Adventure?
At its $10 retail price across 65 pieces, The Swamp Adventure works out to about $0.154 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO The Swamp Adventure a good investment?
The Swamp Adventure currently trades 50.1% above its $10 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 The Swamp Adventure so expensive?
The Swamp Adventure was released in 2023 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.
