Is LEGO Adventure Time retired?
Yes — Adventure Time (21308-1) 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 Adventure Time?
At its $50 retail price across 495 pieces, Adventure Time works out to about $0.101 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Adventure Time a good investment?
Adventure Time currently trades 187.1% above its $50 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 Adventure Time so expensive?
Adventure Time was released in 2016 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.
