| Beschrijving voorzijde | Central field depicts the Great Wall of China rendered in fine relief, with its crenellated battlements and watchtower rising prominently against a plain background. The wall stretches across the lower portion of the coin in a dramatic perspective view. The legend 中华人民共和国 (People's Republic of China) is inscribed in Chinese characters along the upper periphery, reading vertically in traditional orientation. The date 1993 appears in the lower field in incuse serif numerals. The design is executed in a detailed engraving style characteristic of Chinese commemorative gold issues of this series. |

Issued as part of China's early 1990s commemorative science series, this piece honors the mathematical concept of zero — specifically China's historical contribution to its formal definition and positional use. The series was unusual for a central bank program in that it targeted abstract intellectual achievements rather than the political figures or cultural landmarks that dominated commemorative coinage of the period.
Mintage was tightly controlled, as was standard for the PBC's gold commemoratives of this era, keeping surviving populations genuinely small.
