The smallest official subdivision of the Tunisian dinar is the millime.
One Tunisian dinar is divided into 1,000 millimes, making the dinar unusual among currencies that commonly use 100-unit subdivisions. Tunisia introduced the dinar in 1958, replacing the Tunisian franc after the country gained independence from France in 1956.
The Central Bank of Tunisia issues the dinar. Its ISO 4217 code is TND. The word “millime” is related to the French millime, itself connected to the idea of one thousandth. Millime coins have denominations such as 1, 2, 5, 10, 20, 50, and 100 millimes.
The millime can be confused with similarly named minor units elsewhere, including Morocco’s centime and Oman’s baisa. In Tunisia, however, the defining fact is the 1,000-to-1 relationship: 1,000 millimes make one dinar. This structure is useful for prices that would otherwise require fractions of a dinar.
