Is LEGO Space Mining Mech retired?
Yes — Space Mining Mech (31115-1) 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.
Has LEGO Space Mining Mech gone up in value?

What is the price per piece for Space Mining Mech?
At its $25 retail price across 327 pieces, Space Mining Mech works out to about $0.076 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Space Mining Mech a good investment?
Space Mining Mech currently trades 60.0% above its $25 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 Space Mining Mech so expensive?
Space Mining Mech 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.
