A Chinese vase previously thought to be worth just $800 auctioned for $6.1 million on the weekend.
Swiss auctioneer Geneve-Encheres described the 23-inch-high vase as 20th century but bearing an unidentified 18th century marking.
Just two bidders fought it out
Yet two bidders at the Thursday sale were adamant the marking was an original from the 18th century Qianlong era.
It is the latest in a line of "cheap Chinese vase sells for millions" stories in recent years.
Last year an 18th century Chinese vase bought for £12 ($17) in the 1950s auctioned for £900,000 ($1.3m).
The regularity of the tales is great news for charity shops and thrift stores, who no doubt have seen an increased trade in modern reproduction Chinese vases.
