A woman on Antiques Roadshow on Monday was left stunned after she was told a rare wine bottle she purchased for a fiver could actually be worth a lot more.
Speaking to expert Lars Tharp during the BBC show, she explained that she she found the dull coloured sake bottle during a trip to South Japan a few years ago.
Despite paying just £5 for it, she had an inkling that it could be around 150 years old and worth a bit more.
However, she certainly wasn't expecting Lars' response and estimation.
He said: "A very modest little pot, very grey, decoration reserved only on to one side, and you love all the imperfections?
"You bought it in Japan. It could be Japanese, it could be Korean, there is a link between the two."
Despite its duller colour, Lars revealed the sake bottle was made of porcelain and its distinctive shape lead him to believe it actually dated back to 1650 to 1700.
He continued: "So it's a little bit older than your 150 years. How much did you pay for it?"
She replied: "We paid about £5 for it," to which Lars paused and then said: "Ooh! £5 for a 17th century wine bottle."
He then told the guest that Japanese and Korean pieces like her bottle had gone up and down in value over the last few years.
"But I think a Japanese porcelain collector probably would be prepared to pay up to about £500, so we can put two noughts on your purchase price," Lars concluded.
The woman was stunned and responded: "Wow. Yeah, get some sake into it and have it with the next Japanese dinner we cook."
Antiques Roadshow airs on Sundays on BBC One.
