5 Zhu 'Eastern Han' type, with dot

The dot added to the obverse field of this late Eastern Han wu zhu is not decorative — it almost certainly marks a specific foundry or casting batch, a practice used intermittently across the Han period to track production sources when central monetary authority was fragmenting. By the mid-second century, imperial control over coinage had weakened considerably, with regional warlords and commandery administrators increasingly operating their own casting operations ahead of the collapse that brought the Three Kingdoms period.
