10 Shillings - British Armed Forces 2nd series

British Armed Forces Special Vouchers — universally called BAFSVs — existed specifically to prevent sterling from leaking into local economies near British military bases. Servicemen were paid in vouchers rather than sterling, and those vouchers could only be spent in NAAFI canteens and on-base shops. Any local trader caught accepting them faced serious penalties. The second series replaced the first after currency manipulation by troops and locals during the Korean War period exposed weaknesses in the original issue.

De La Rue printed the series under tight security. Serial number blocks were tracked closely — irregular sequences can sometimes indicate replacement notes, though documentation at this granular level remains patchy.
