500 Wu Zhou Wu

The State of Wu was the last of the Three Kingdoms to fall, holding out against Jin until 280 AD while the northern states had already collapsed. Wu coinage from this period is notable for its debasement trajectory — the 500-cash nominal value on these bronzes bore no relationship to their actual metal content, a fiscal fiction the Wu government sustained through increasingly thin issues as military pressure mounted from the north.

Schjoth 193 places this squarely among the larger-denomination issues the Wu court used to stretch its treasury.
