Rare Cechoslovak stamp sold at auction for over 1.7 million crowns
One of the rarest Czechoslovak stamps was sold at an auction in Prague on Saturday for more than 1.7 million crowns (some 63,000 euro). The starting price was at one million crowns. The 50-heller was issued in 1927 and by mistake, overprinted “50/50” DOPLATIT as a postage due. It was used by the post office before the error was discovered. Between 20 to 30 used copies are believed to be in the possession of collectors.
