35 dollars at a garage sale in Connecticut, in the northeast of the United States, is going to be put under the hammer at Sotheby's for an estimated value between 300,000 and 500,000 USD. The lucky "discoverer", whose name has not been revealed, had the bowl with delicate floral motifs appraised by the auction house, first by sending photos, then by bringing the object itself; it turns out that it dates from the 15th century and that it was painted for the court of Emperor Yongle, third emperor of the Ming dynasty. Its "very distinctive" shape and floral pattern place it in an extremely rare bowl category - only six other comparable bowls have been identified in the world. Of those six, five are in museums - two in Taipei, two in London, one in Tehran. The sixth was' last seen on the market in 2007. But we're here to talk about coins, aren't we ? Do you have in your collection a coin that you bought and underestimated the value ? Please show me your MING coins ! Two of mine, don't know their real value (anyway don't want to sell them), but they certainly worth a lot more than I paid (from "uncleaned" lot).
