In 1992 the first Inventions and Discoveries of Ancient China series was issued by the People’s Bank of China. The series includes thirty coins, of which seven are gold, eighteen are silver, and five are platinum. Pictured above are the five 1 oz 100 yuan gold coins from the series. Each of the five coins is certified to be of proof quality and to have a purity of 99.9%. They measure 32mm in diameter, have mintages of 1,000 pieces each, and were struck at the Shenyang mint.

The series celebrates five inventions, discoveries, and archeological finds from ancient China: the seismograph, invented in the 2nd Century AD by Zhang Heng (78-139 AD) – a famous Han Dynasty polymath; the kite, invented in the 4th Century BC and attributed to the philosopher Mozi (470-391 BC); navigation and shipbuilding in the 2nd Century AD; the invention of the compass in the 4th Century BC; and Bronze Age art dating from around the 16th Century BC.

Featured on the reverse faces of the coins are depictions of the five discoveries mentioned above with inscriptions in Chinese characters giving the name of the discovery and its approximate dates. The denomination of the coins, 100 yuan, also appears on the reverse faces.

The design featured on the obverse face is an image of the Great Wall. The Great Wall was initially built during the Qin Dynasty (221-206 BC) and following extensive upgrading, rebuilding, and modifying, especially at the time of the Ming Dynasty (1368-1644), became an impressive and internationally recognised symbol of Chinese power and achievements. Its primary purpose was to provide a line of defence against the tribes to the north of the Chinese empire and also to control trade. Above the image of the Great Wall is the inscription in Chinese: “The People’s Republic of China”. Below the image is the year of production, 1992.
