Country codes of Serbia
This code is used for national currency, in this case the Serbian dinar. This three-letter code is composed of, by rule, first two letters of the ISO 3166-1 alpha-2 and a third letter is initial of the currency itself: codice_40. Exceptions from the rule are made only in the third letter, if that suits the country better — however that is not the case here.
