10 Piastres Helwan; R.A.F. Station

The RAF base at Helwan, roughly 25 kilometres south of Cairo, operated as a major British air station throughout the Western Desert campaign. Mess currency of this kind was a practical response to chronic small-change shortages in wartime Egypt — Egyptian piastre coins had a habit of disappearing from circulation during the war years, and units issued their own scrip rather than depend on the local economy for petty transactions within the mess.

Officers' mess tokens rarely survived demobilization. They were redeemed, discarded, or pocketed as curiosities when a station closed or personnel rotated out. The grey paper stock was deliberately unglamorous — these were functional instruments, not intended to outlast the posting.
