Guests on Antiques Roadshow were left utterly gobsmacked when a valuation far exceeded expectations during the show's visit to Thirlestane Castle in the Scottish Borders.

Notable experts gracing the episode included Katherine Wright, Charlotte Riordan, Adam Schoon, and Mark Smith, alongside journalist and renowned antiques aficionado Marc Allum.

Marc encountered a mother and son duo in possession of familial heirlooms from a long-forgotten Russian ancestor.

Marc couldn't hide his enthusiasm for their historical assortment, which featured a grand portrait, a miniature painting, and an opulent gold snuffbox, believed to be a gift from a Russian tsar.

The snuffbox in particular piqued Marc's interest he meticulously detailed its key attributes to the guests.

Included with the box was a note detailing an engraving originally inscribed upon it.

When quizzed about the "value" of their heirlooms, the guests professed to have held only sentimental considerations, placing no thought on monetary worth.

The revelation of the snuffbox's potential value estimated by Marc at a staggering £20,000 to £30,000 elicited sheer amazement from the guests.

One remarked in disbelief: "That's quite a lot for a little box, isn't it?!", reports .

Marc affirmed, with a tone of admiration: "But it's a little box with great history attached to it. So thank you, it's been lovely to talk about it."

Over at Thirlestane Castle, antiques expert Raj Bisram was left in awe when presented with a Rod Stewart gold disc that once belonged to the late footballer Sandy Jardine.

The guest recounted the fascinating tale behind the item, saying: "Well, Sandy Jardine's my husband, he died ten years ago. Many years ago, he and Kenny Dalglish were very close friends with Rod Stewart.

"And they were out having a carry-on, as we do in Scotland and Rod Stewart said, 'You know, I would love to have a Scot, you know a Scottish cap, Sandy'.

And he goes 'Well, I would like to have a gold disc'. Well, it actually came to, for there we are."

The story continued with the guest explaining how Rod and Sandy ended up doing a "swap" of their prized possessions.

Raj estimated the value of the gold disc to be between £1,500 and £2,000, much to the delight of the guest.
