Frequently asked questions
How much is LEGO Alien Moon Stalker (6940-1) worth?
LEGO Alien Moon Stalker is worth approximately $737 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Alien Moon Stalker retired?
Yes — Alien Moon Stalker (6940-1) 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.
Why is LEGO Alien Moon Stalker so expensive?
Alien Moon Stalker was released in 1986 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.
