Overview
A cast bronze currency piece featuring the 'Zhi Dao Yuan Bao' inscription in a distinct running-hand or grass-script calligraphy. These coins were the backbone of the world's first truly sophisticated paper-and-metal monetary system.
Story
Emperor Taizong himself is credited with writing the calligraphy for these coins. This wasn't just money; it was a piece of imperial art circulated to millions. It represents a golden age of Chinese economic expansion.
Maker / Origin
The Northern Song mints were marvels of early industrial production, utilizing mother-cash models to cast thousands of identical coins. The calligraphy reflects the Emperor's personal hand, a tradition known as 'Yu Shu' or Imperial Writing.
Condition & Value
The coin shows significant green oxidation (verdigris) and surface wear consistent with burial or long-term circulation. The framing has preserved the script's legibility, which is the primary value driver for this type. Wear reduces numismatic grade but adds 'relic' appeal.
