€ EUA (European Unit of Account) adalah cikal bakal euro, sesuai dengan keterangan wikipedia (lihat surjaya). (Frasa at parity di situ berarti 1 EUA = 1 ECU = 1 euro; lihat http://www.investopedia.com/terms/p/parity.asp )

☕ Karena menyatukan sekeranjang mata uang (a basket of currency), boleh dikatakan bahwa ini adalah mata uang komposit.

↪ Contoh lain mata uang komposit adalah SDR, yang dibuat oleh IMF dari empat mata uang utama: $, €, ￥, dan £

https://en.wikipedia.org/wiki/European_Unit_of_Account
The European Unit of Account (EUA) was a unit of account used in the European Communities from 1975 to 1979, when it was replaced at parity by the European Currency Unit, in turn replaced at parity in 1999 by the euro.

... The EUA was a basket of European currencies, originally designed to have the same value in mid-1974 as the IMF special drawing rights basket....

The bonds were denominated in the composite currency, European Units of Account (EUA).

ECU adalah mata uang komposit yang merupakan penjumlahan dari mata uang 12 negara Eropa.

Catatan: ECU adalah pengganti EUA secara 1-banding-1 (at parity)

A better example of a composite currency is found in the SDR. SDR stands for special drawing rights. It is a composite currency created by the International Monetary Fund (IMF). One SDR currently consists of a fixed quantity of US dollars, Euros, Japanese yen, and British pounds.

Karena EUA sendiri sudah menjadi mata uang seperti SDR, saya rasa tidak usah diterjemahkan, namun diberi keterangan. Bentuknya adalah:

mata uang komposit Eropa EUA (European Unit of Account, E.U.A.-9)

Analoginya: mata uang Indonesia IDR (Rupiah Indonesia)
