The Luxembourg franc (F or ISO LUF, Luxembourgish: Frang), subdivided into 100 centimes, was the currency of Luxembourg between 1854 and 2002, except from 1941 to 1944. From 1944 to 2002, its value was equal to that of the Belgian franc. The franc remained in circulation until 2002, when it was replaced by the euro.

The Belgian franc was the currency of the Kingdom of Belgium from 1832 until 2002 when the Euro was introduced. It was subdivided into 100 subunits, each known as a centiem in Dutch, centime in French or a Centime in German.
