1 Shilling - British Armed Forces 2nd series

British Armed Forces Special Vouchers were introduced to prevent servicemen stationed abroad from accessing local currency markets, disrupting exchange rates, or facilitating black market activity — a serious concern in occupied Germany and across British garrison territories in the late 1940s. The 2nd series replaced the 1st after security concerns prompted a redesign; the earlier vouchers had proven vulnerable to forgery and unauthorized accumulation by local civilians who found ways to exploit them.

BAFSV notes were non-convertible outside military channels and periodically demonetized without warning, a deliberate feature that made hoarding strategically pointless.
