1 Euro Cent (2002-Present)
The smallest of the circulating euro coins, the diminutive 1 euro cent has virtually no purchasing power but, much like the cent in the United States, it circulates widely as a change-making coin. The 1 euro cent replaced the 10 groschen as Austria’s lowest value circulating coin when the Alpine country switched to the euro in 2002.
