A rare, Royal Worcester porcelain wine funnel made £10,000 ($15,259) at UK auction house Tamlyns on July 2.
Previous to the sale, the vendor, who hails from Bridgwater, Somerset, had no idea as to the item's value.
A spokesperson for Tamlyns told local newspaper the Bridgwater Mercury: "It was always understood in her family that it was Worcester but they had never had a definite attribution.
"Amazingly given its age, and the fact that it had been used, the funnel was in almost perfect condition."
A single telephone bidder and a buyer present at the sale battled against one another, driving the item's price ever higher.
The anonymous telephone bidder eventually won the rare item.
