Frequently asked questions
How much is LEGO T-Rex (4078-1) worth?
LEGO T-Rex is worth approximately $12 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO T-Rex retired?
Yes — T-Rex (4078-1) 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 T-Rex so expensive?
T-Rex was released in 2001 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.
