As i remember about living in Mozambique is that the currency is such that $100 = $1.1M Mozambique Metacal. Looking on Oanda it looks like they have a "new" currency that is $1 to M$28 so that might help but I lived at the Polana (old one) for 4 months and they used US currency in their casino. Really nice place, surprised they have a "new" one according to Carlos' pictures.
