10 Buqshas

Yemen's first central bank notes, introduced following the 1962 revolution that ended Mutawakkilite Kingdom rule, replaced the old Maria Theresa thaler-based system with a decimal one. The buqsha — one-fortieth of a rial — was itself a short-lived unit; this denomination disappeared from circulation relatively quickly as inflation made small-value notes impractical.

Bradbury Wilkinson's New Malden facility handled security printing for numerous newly independent states through the 1960s, and the Central Bank of Yemen was among their standard postcolonial clientele. The watermark is the sole security feature — modest even by the standards of the period.
