Currency codes
ISO's currency codes, which are based on the ISO country codes are published in the standard ISO 4217:2008 Codes for the representation of currencies and funds.
This International Standard specifies the structure for a three-letter alphabetic code and an equivalent three-digit numeric code for the representation of currencies and funds. For those currencies having minor units, it also shows the decimal relationship between such units and the currency itself.
