5 Yuan Huang Dao Po

Huang Daopo, the 13th-century cotton textile innovator credited with revolutionizing weaving and ginning technology in the Yangtze Delta, was commemorated in this series as part of China's broader 1980s program honoring historical scientists and inventors. The series was explicitly designed for international collector markets during a period when China's state mint was aggressively expanding foreign exchange revenue through numismatic exports.

Dies for this type are known to exhibit minor positional inconsistencies in the field due to the transitional production methods at the Shanghai Mint during this period.
