I went on Antiques Roadshow but was completely caught off guard by a strict rule

An Antiques Roadshow guest got more than they bargained for after being caught off guard by a stern rule on set. While on set of the American spin-off of the BBC hit show, she was also left shocked at the valuations of her objects.

Journalist Jennifer Kopf bagged an invite to be part of the up and coming series recorded at Grant's Farm in St. Louis. The Country Living writer rocked up with a framed silhouette and blue glass lamps, eager to discover their worth.

She revealed that depending on the category your item falls into, you end up speaking to an expert appraiser from that field in an area 'spread out all across the grounds'.

To avoid spoilers getting leaked, she revealed that there was one order that she had to follow while she was there.

Jennifer wrote for the mag: "Set up in between were three different filming 'studios' with those famous tables arranged for the big-time appraisals.

"I wasn't allowed to tape anything happening on set so as not to take away anything from the big reveals come air time."

Turns out her haul wasn't worth what she hoped with her framed silhouette snatching a modest $25 to $50 tag.

However, what really 'hurt' was the lamp letdown. Jennifer confessed: "$15 a piece. I have to admit, this hurt a little. But I still love my lamps and will find a perfect spot for them soon."

It comes after an Antiques Roadshow guest was left gobsmacked after a family ring, long thought to be a cheap piece of costume jewellery, turned out to be a rare and valuable emerald piece worth more than expected.

The jaw-dropping revelation occurred during an episode first broadcast in October 2022, which was repeated on Sunday (15 June).

John Benjamin left one family utterly shocked. The guests, two cousins, presented a collection of inherited treasures passed down through generations.

Among the assortment was a gold novelty pencil, a decorative brooch depicting a fly on a flower, and the green stone ring under scrutiny.

Discussing the origins of the items, the guests revealed that many were from their great-great-great grandmother, who was born in 1858. One item, a mountaineer's ice pick-shaped pencil, bore the names of French mountains.

The biggest revelation came with the green stone ring that the family had always assumed was costume jewellery. He valued the ring at a whopping £4,000. In total, the collection was given an estimated auction value of £7,000.

Antiques Roadshow is available to watch on BBC One and iPlayer
