The Croatian National Bank may destroy unfit coins through the process of demonetisation.
Through the process of demonetisation unfit coins are subject to irreversible physical deformation, for example: corrugation, elongation, milling, clipping of edges, imprinting of a rhomboid net so that the same coins cannot be recirculated or submitted for replacement.
Demonetised coins are not a legal means of payment in the Republic of Croatia nor are they replaced for fit coins.
