The returned "currency" values can be used with NumberFormat.

Intl.supportedValuesOf ( key )
1. Let key be ? ToString(key).
...
4. Else if key is "currency", then
a. Let list be ! AvailableCurrencies( ).
...
9. Return ! CreateArrayFromList( list ).
AvailableCurrencies ( )
The AvailableCurrencies abstract operation returns a List, ordered as if an
Array of the same values had been sorted using %Array.prototype.sort% using
undefined as comparefn, that contains unique, well-formed, and upper case
canonicalized 3-letter ISO 4217 currency codes, identifying the currencies
for which the implementation provides the functionality of Intl.DisplayNames
and Intl.NumberFormat objects.

// which may depend on x in languages having different plural forms. If the
