Is LEGO The Mountain Cave a good investment?
The Mountain Cave currently trades 450.7% above its $250 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 Mountain Cave so expensive?
The Mountain Cave was released in 2017 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.
