A woman in Somerset, England, discovered she had a rare Italian Renaissance Maiolica plate hanging on the wall of her cottage when she invited appraiser Richard Bromell of Charterhouse Auctioneers in Sherborne, Dorset, to assess some of the objects in her home for their market value. It was hanging in a makeshift wire frame behind a door that was always open. Only about two inches of it were visible when Bromwell caught a glimpse of it.Text and image from The History Blog, where there is additional information about the events depicted on the plate.
At first he thought it had to be a 19th century reproduction worth perhaps £2,000 ($3,100), but when he took it to experts at the Ashmolean Museum they confirmed that it was the real thing: a Maiolica charger made in Urbino around 1540. The owner had inherited it from a relative years ago and had no idea of its age or value. It was put up for auction at Charterhouse on February 14th with a pre-sale estimate of £100,000 ($155,000), but due to massive interest from bidders all over Europe and the US, the final hammer price was an astonishing £567,000 ($880,000).
