Imagine buying a painting and then being told its worth 1,000 times what you paid for it.
That's what happened on the British version of "Antiques Roadshow."
The owner paid $660 for a portrait that turned out to be the work of 17th century Flemish artist Anthony van Dyck.
It's considered a masterpiece and it's valued now at $660,000!
The owner, a priest, says he wants to sell the painting to buy new bells for his church.
