What is the price per piece for Mountain Windmill?
At its $180 retail price across 2,085 pieces, Mountain Windmill works out to about $0.086 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Mountain Windmill a good investment?
Mountain Windmill currently trades 122.2% above its $180 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 Mountain Windmill so expensive?
Mountain Windmill was released in 2021 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.
