Frequently asked questions
How much is LEGO Transformer 12V (741-1) worth?
LEGO Transformer 12V is worth approximately $124 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Transformer 12V retired?

Why is LEGO Transformer 12V so expensive?
Transformer 12V was released in 1974 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.
