The subject of study of monetary economy is money, its forms and functions and its economic and reproductive role. Since modern money is a very heterogeneous category, an adequate money issue policy makes it possible with particular forms of money to achieve some additional effects. This primarily refers to commemorative coins, the issue of which may bring significant economic effects based on numismatic designs. In this way, this kind of money may get another role in monetary economy. Such approach does not lessen the basic functions of commemorative money, such as the function of preserving value, the function of a means of transaction, the function of a means of payment or its commercial function. Planned activities in relation to the introduction of cash money, including commemorative coinage, iil most European Union countries in the year 2002, among other things, will also have important influence on Croatian money issue policy regarding commemorative coinage. The reasons for this are the development of money issue activities in the sphere of coinage, especially in the segment of commemorative coins in the European Union countries, and the readiness of Croatia to participate in that association. It will therefore be necessary to harmonize Croatian money issue policy in the sphere of commemorative coinage with the unified policy of these countries that is now being profiled.
