5 Dinars Independence 20th Anniversary

Tunisia's twentieth independence anniversary in 1976 fell during Bourguiba's single-party consolidation, when commemorative silver issues served a direct propaganda function — projecting stability and national identity for both domestic and foreign audiences. The .680 fineness is a deliberate cost compromise, common across Tunisian commemorative silver of the 1970s, keeping the series accessible for diplomatic gift sets while retaining precious metal content.
