The BBC reports that the most valuable item ever featured on 38 years of Antiques Roadshow is estimated to be worth more than £1 million.

The item, described by producers as ‘a world famous piece owned by a sporting institution’, was discovered during filming in north Yorkshire, although the exact description and details of the item won’t be revealed until the programme screens next April.

A spokesman for the BBC1 programme said: “An item seen at the Antiques Roadshow in Harrogate is the highest valued object ever to appear on the show in its 38-year history… It is a world-famous piece owned by a sporting institution.

“The final valuation given will be revealed when the programme airs in spring 2016.”

The previous record was the 2008 £1 million estimate for one of Antony Gormley’s models of the Angel of the North, which was three times the show’s previous record.

Antiques Roadshow is hosted by Fiona Bruce.
