1 Rial

Yemen's 1993 coinage came in the immediate aftermath of unification — the Republic of Yemen had formally merged North and South only in 1990, and the Central Bank was still consolidating two separate currency systems that had operated under entirely different political economies for decades. The Southern rial had been backed by a Marxist state; the Northern by a republic with Gulf patronage. Getting a single circulating coinage accepted across both territories was not a given.

KM#25 is specific to the unified republic's early emission series.
