Unofficial codes for minor units of currency Minor units of currency (also known as currency subdivisions or currency subunits) are often used for pricing and trading stocks and other assets, such as energy, but are not assigned codes by ISO 4217. Two conventions for representing minor units are in widespread use: Replacing the third letter of the ISO 4217 Code of the parent currency with an upper-case "X". Examples are GBX for penny sterling, USX for the US Cent, EUX for the Euro Cent. Replacing the third letter of the ISO 4217 Code of the parent currency with the first letter of the name of a minor unit, using lower-case. Examples are GBp for Penny Sterling, USc for the US Cent, and EUc for the Euro Cent.
