Frequently asked questions
How much is LEGO Steam Locomotive (721-1) worth?
LEGO Steam Locomotive is worth approximately $707 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Steam Locomotive retired?
Yes — Steam Locomotive (721-1) 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 Steam Locomotive so expensive?
Steam Locomotive was released in 1969 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.
