5 Zhu 'Eastern Han' type, with radiate lines

The radiate lines variant of the Eastern Han 5 zhu represents one of the final expressions of a denomination that had anchored Chinese bronze coinage for nearly four centuries. By the late second century, central Han authority was collapsing under the pressure of warlord fragmentation, Yellow Turban uprisings, and the slow dismemberment of imperial administration that would formally end with the abdication of Emperor Xian in 220. Coinage quality deteriorated accordingly — flans thinned, copper content dropped, and regional casting introduced the kind of stylistic irregularities that distinguish late Han pieces from their crisper predecessors.

The radiate lines around the central square hole are a late typological detail, likely a casting artifact that became a recognized regional feature rather than an intentional design choice.
