Tom Keating's View of Santa Maria della Salute and Grande Canal, Venice, was sold to a London buyer when it went under the hammer in Northamptonshire.
The painting was presented to the Antique's Roadshow in the 1990s by a viewer who was unsure of its worth.
Auctioneer Jonathon Humbert said the unsigned work sold on Friday was a very close likeness to the original.
Keating, who died aged 67 in 1984, hit the headlines in 1979 when he admitted nine paintings said to be drawings by Samuel Palmer were, in fact, his copies.
He maintained his motives were not for profit, but to expose the fallibility of art experts.
He never signed his paintings with either his name or the name of the artist he was copying.
His notoriety led to his own work becoming popular and in 1983 Christie's auctioneers sold 135 of Keating's paintings for £72,000.
