From Wikipedia:
The dirham was reintroduced on 16 October 1960. It replaced the franc as the major unit of currency but, until 1974, the franc continued to circulate, with 1 dirham = 100 francs. In 1974, the santim replaced the franc. In 1974, with the introduction of the santim, a new coinage was introduced in denominations of 1, 5, 10, 20 and 50 santimat and 1 dirham. The 1 santim coins were aluminium, the 5 up to 20 santimat were minted in brass, with the highest two denominations in cupro-nickel.
