25 Dinars

Sudan established its own currency printing facility in Khartoum largely to reduce dependence on foreign printers — a politically charged decision given the country's post-independence sensitivity around economic sovereignty. The Sudan Currency Printing Press has handled most domestic note production since the 1970s, though quality consistency across series has been uneven, and the 1992 issues are no exception.

The 1992 series appeared during a period of accelerating inflation that would eventually force wholesale redenomination. This 25 Dinar note was rendered effectively obsolete within a few years of issue.
