In a repeat showing of the long running BBC One programme a member of the public was left “shaking” after an expert valued it at the Eden Project in Cornwall.

The woman, who was not identified, told expert Andy McConnell: “It belongs to my father, he saw it on a bric-a-brac stall, [the owner] wanted 10p, my father liked it so gave him 50p”.

Amazed at the story, Andy jokingly said: “Oh I really like it, can I have it for a quid?” before going on to reveal the wine glass’ origins.

Andy said it was called a “heavy baluster” as the glass used contained 30 per cent lead, and said it dated back to 30-years after the invention of lead crystals.

He said: “George Ravenscroft perfects the formula for lead crystal in 1676, and this is 30-years afterwards.

“It’s about 1705-1710, which dates it at over 300-years old.”

Not only that, Andy said, but it was rare, as the owner admitted the news had left her shaking.

He put the valuation at an incredible £2,000, with the woman putting her hand to her mouth in amazement.

Concluding the segment Andy said: “Have a drink out of it tonight for Dad”.

The episode originally aired a year ago.

Elsewhere, an Antiques Roadshow guest begged “don’t tell my wife” after he found out the jaw-dropping value of his “gold dust” print.

Another guest wasn’t so happy with their valuation for his precious “£250k item.”

On a seperate episode of the Antiques Roadshow, a guest was left gobsmacked after learning the value of a broken watch he had found in a box of junk.

In another edition, a pensioner was left speechless after discovering the whooping value of her own nude portraits from 1970.
