When was Zhang Heng's stamp issued? How many copies were issued?
Almost all stamp sheetlets in the history of new China stamp issuance are in sets, but the 33M stamp sheetlets (the first group) are in sets of four. China Ancient Scientists 1956 65438+ 10 1 day was released, and New China issued four 8-cent sheetlets, which were composed of paleoastronomer Zhang Heng, paleomathematician Zu Chongzhi, paleontologist Li Shizhen and paleoastronomer Xing Monk.

As for the number of stamps issued, it is still a mystery because the number of prints has not been clearly indicated in the stamp catalogue of New China for a long time. According to industry estimates, the number of stamps issued is about 250,000 sets, with a large number of stamp sheetlets and souvenir sheets. Because the post office cancelled some of them, it is estimated that the actual number of new stamps will exceed 6.5438+0.7 million sets, which is not too high for stamp owners.

The ticket has been issued for more than 50 years, starting from 0.32 yuan, and the price has been rising for decades. At the third climax of the postal market in March, 1997, the price rose by more than 800 yuan. With the weakness of the whole postal market, the price of air tickets has fallen sharply. Since the second half of last year, air ticket prices have rebounded strongly in 350 yuan. At present, the new price is around 620 yuan. Seven special stamp sheetlets and souvenir sheets were issued in New China. The prices of several souvenir sheets issued in the Monument to the People's Heroes are still relatively low. The price of a souvenir sheet of Guan Hanqing's Seven Hundred Years of Drama Creation is also more than 1400 yuan; The price of Mei Lanfang's stage art sheetlet is as high as 37,800 yuan. This shows that the price of a set of China Ancient Scientists is obviously low, and its value is seriously underestimated by the market. The author firmly believes that with the gradual improvement of the postal market and the strengthening of people's investment concept, the price of a set of unique sheetlets will definitely reach a new level.
