5000 Customs Gold Units

The Customs Gold Unit (CGU) was introduced in February 1948 as an accounting currency for tariff collection, intended to insulate customs revenue from the catastrophic hyperinflation already consuming the standard fabi. It was a stopgap with a short life — by August 1948 the entire CGU system was swept aside when the Nationalist government launched the Gold Yuan reform, another failed attempt to stabilize a collapsing monetary situation.

ABNC printed this series under wartime-era contract arrangements that had never fully normalized after 1945. The 5000 CGU denomination reflects just how quickly the unit's purchasing power eroded even within its brief existence.
