A Palitoy 30B Back Boba Fett Star Wars figurine has sold for ?�18,000 ($27,244) at Vectis Auctions in Thornaby, UK.
The rare lot was released by Palitoy in 1978.
Less than a year later the company's licence ran out. Few remain in mint condition.
Consignor Craig Stevens, former president of the UK Star Wars Fan Club, told the BBC: "You think to yourself, 'I'm in a [rented] flat and I have got a box of figures worth as much as a house'.
"There's no contest, really."
The sale eclipsed the auction of a Palitoy Jawa figurine, which made ?�10,200 ($16,500) at Vectis last year.
