Note for collectors: In colonial-era Korea (1910-1945) and Taiwan (1895-1946), the sen was used primarily as a unit for banknotes and stamp currencies rather than locally minted coins.
SEN as a coin name: Across different countries, the etymology of the name can be divided into two groups. For Japan, Korea, and Taiwan, it derives from the Chinese character "qian" (銭), meaning "money" or "coin." Conversely, the sen of Malaysia, Brunei, Indonesia, and Cambodia originated as regional adaptations of the colonial cent or centime.

The Japanese Sen: Rise and Withdrawal

The sen was officially introduced in 1871 during the Meiji Restoration, establishing a modern decimal system: 1 yen = 100 sen = 1000 rin. This reform aligned Japan with Western decimal standards while retaining traditional terminology.

For decades, sen coins struck in copper, nickel, and silver (like the Taishō issues) were the backbone of daily retail transactions in the Empire. However, hyperinflation following World War II stripped the sen of its practical purchasing power. In 1953, the Japanese government officially withdrew the sen from circulation, making the yen the sole unit for daily cash use. Today, the sen survives only as an accounting unit in financial markets and historical contexts.

The Sen in Southeast Asia and Modern Circulation

In contrast to Japan, the sen remains a vital part of the modern economy in countries like Malaysia and Brunei. In Malaysia, 1 ringgit = 100 sen, with coins regularly minted in nickel-plated steel featuring national flora like the hibiscus and Islamic geometric patterns.

Historically, the sen also circulated in Indonesia and Cambodia as they transitioned to sovereign currencies (the rupiah and riel). While inflation has made low-value coins less common — and in Indonesia's case, physically obsolete — the unit remains the official structural subdivision of their monetary systems.

Collectibility and Artistic Value

Japanese sen coins from the Meiji and Taishō eras (1870-1926) are especially prized for their intricate artistic designs and silver content. Collectors particularly value denominations like the 20 and 50 sen for their rich imperial symbolism, including the chrysanthemum crest and mythical phoenixes. These coins represent a complete record of a nation's transition from traditional cast money to a globalized modern currency system.
