6 Zhu Southern dynasties, Southern Chen

The Southern Chen was the last and weakest of the four Southern Dynasties, squeezed into the lower Yangtze basin while the north consolidated under Northern Zhou and then Sui. This issue dates to the reign of Chen Xuandi, a period of relative administrative stability before Sui Wendi's 589 conquest extinguished the dynasty entirely. The 6 Zhu denomination itself was a practical compromise — an attempt to stabilize a debased bronze currency that had deteriorated badly across the Southern Dynasties period, with lighter and thinner castings having progressively undermined public confidence in copper coinage.
