5000 Roubles Voucher; Cooperative of the Military Medical Supplies Plant Z.V.V.Z.; Petrograd

Z.V.V.Z. — the abbreviation expands to Zavod Vojenno-Vrachebnych Zagotovlenij, the Military Medical Supplies Plant — was among hundreds of Petrograd industrial enterprises that issued internal cooperative scrip during the early Soviet period when state wages arrived late, irregularly, or not at all. These vouchers functioned as canteen and store credit redeemable only within the factory's own cooperative shop, a parallel micro-economy born entirely from the chaos of War Communism.

The 5000-rouble denomination reflects the extreme inflation of 1920, when the Soviet rouble had collapsed so severely that five-figure sums bought little.
