|System||1 Diner = 100 Cèntims|
The Andorran Diner (unofficial code ADD), called Diner andorrà in Catalan, is a commemorative currency issued in form of coins intended for collectors and without a legal tender value. A diner is divided into 100 cèntims. The name diner (money in Catalan) is derived from the Roman currency denarius.
The Servei d'Emissions de la Vegueria Episcopal has issued from 1977 onwards various series of diner denominated coins. Previously there were minor privately issued diner coinage (with no legal value). There have been silver, golder and bimetallic issues. The most commemorated topic is Charlemagne.
The exchange rate was defined (informally) as 100 ESP (0.60 EUR) or 5 FRF (~125 ESP or 0.75 EUR) to one diner. However, there is no bank or other authority where visitors to Andorra can change diners for euros, it is only an informal relation. It is not possible to buy anything with diners in Andorra - this is only an artificial currency to produce commemorative coins.
