The FDC with coin could not be released during the Expo, but after the Expo. Usually, the mintage of FDC with coin is 5,000-10,000. It takes time to prepare the package. The coin is sealed on a long hard plastic sheet (the same size as envelop) and placed in envelop. China National Philatelic Corporation obtains the postal seal at the first day of Expo and make the package later.
