We are talking about units in currency correct, one 25000 dinar note is = to twenty-five thousand 1 dinar notes. The only way they can change the value of any of thier currency is to change to value of one unit. If they say that a 25000 dinar note is only worth 25 dinars now then they have devalued all there currency by a 1000%, and if they do that then they will not be able to afford to import anything.
