is this answer ok?

The Moroccan dirham is the official currency. Bills come in denominations of 20, 50, 100 and 200 dirhams. Coins come in denominations of 1, 2, 5 and 10 dirhams (there are two kinds of 5-dirham coins). Dirhams are divided into 100 centimes; there are 5-, 10-, 20- and 50-centime (half-dirham) coins.

It is illegal to import or export Moroccan dirhams. Upon leaving Morocco, tourists can reconvert only up to 50 % of the dirhams for which they have exchange slips at the bank at the airport.

PS:

if you have moroccan bank account you can always transfer money back to UK
