Frequently asked questions
How much is LEGO 4.5V Battery Case (101-3) worth?
LEGO 4.5V Battery Case is worth approximately $35 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO 4.5V Battery Case retired?

Why is LEGO 4.5V Battery Case so expensive?
4.5V Battery Case was released in 1966 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.
