11. Clyfford Still painting – $500,000 (U.S. series, 2009)
The U.S. version of Roadshow has only been going since 1997, but it didn’t take long for items worth six figures to start turning up. In 2009 the record for most valuable item was broken by a Clyfford Still painting that was valued at $500,000. The painting may have been worth even more, though, as another Still piece had been auctioned off for $21 million at around the same time as the episode aired.
10. Antony Van Dyck’s “Magistrate of Brussels” – $520,000 (U.K. series, 2013)
The hosts of Antiques Roadshow don’t tend to be experts themselves, but every now and again they get the chance to drop some knowledge. In 2013 U.K. presenter Fiona Bruce had been working on an episode of Fake or Fortune? about artists Antony Van Dyck. As a result, she noticed immediately when one of his unfinished portraits appeared on Roadshow. It was valued at $520,000, but it failed to sell at a London auction in 2014.
