Zusammenfassung:	FIELD: production of intermediate products of coins and counters used in automatic devices and in performance of accounting and control operations. SUBSTANCE: monetary material includes internal layer made of commercially pure aluminium and two cladding layers made of alloy based on nonferrous metals taken from group containing brass, bronze, cupronickel alloy and german silver. Thickness of each cladding layer amounts to 1-20% of thickness of internal layer. Cladding layers are of similar thickness. EFFECT: monetary material combines in itself low density, higher resistance to deformation and prolonged service life. 3 cl
