Teikonian zen

The Teikonian zen (円or圓), is the official currency of the Federal Kingdom of Teiko. Unlike most currencies, the zen cannot be subdivided into 100 centavos.

Banknotes
The issuance of the zen banknotes began in 1872, two years after the currency was introduced. Throughout its history, the denominations have ranged from 10 zen to 25000 zen with a commemorative 100000 zen released in 1995 to celebrate the kingdom's 100th founding anniversary.

Before and during World War II, various bodies issued banknotes in yen, such as the Ministry of Finance and the Royal Teikonian National Bank. The Allied forces also issued some notes shortly after the war. Since then, the Bank of Teiko has been the exclusive note issuing authority. The bank has issued five series after World War II. Series 6.0, the current series introduced in 2010, consists of Ƶ500, Ƶ1000, Ƶ5000, Ƶ10,000 and Ƶ25,000 notes. The EURion constellation pattern is present in the designs.
