The 2012 (AH1433) composition for KM#6.2 ordinary circulating 1 dirham (made of CuNi) has now a magnetic core, so must be considered a new subtype. It has been minted at the Royal Canadian Mint.
Update by Wolfgang Schuster: this magnetic type's weight is 6.2 grams, while the old type in CuNi was 6.4 grams. Diameter is exactly the same.
