| Additional information |
Lü Zhi — the Empress Dowager who effectively ruled the Han court following Liu Bang's death in 195 BC — authorized a dramatic debasement of the bronze coinage in 186 BC, reducing the half-liang standard from its nominal twelve-zhu weight down to eight zhu. The move was economic pragmatism under a regent consolidating power, not a monetary accident. Her administration produced several overlapping weight standards in quick succession, which is precisely why this type sits outside Hartill's main sequence.
The reign lasted only until her death in 180 BC, when the Liu clan moved immediately to suppress her family's influence and restabilize the currency.
