The North Yemeni rial was the official currency of North Yemen from 1965 until unification with South Yemen in 1990. During this time, the currency was also known as the Yemeni dinar, as well as the Yemen Arab Republic rial. These names were used interchangeably depending on the political situation at the time. Today, the currency of Yemen is known as the Yemeni rial, which has been used since unification. It is important to note that the North Yemeni rial is no longer in circulation, and any remaining banknotes or coins can only be found in collections or museums.
