2 Euro Coin – Bertha von Suttner Type (2002-2004, 2006, 2008, 2010-Present)
The 2-euro coin is a bimetallic coin composed of a nickel-brass center with a copper-nickel outer ring. Along with the 1-euro coin, the 2-euro coin forms the backbone of eurozone coinage. The 1-euro and 2-euro coins are similarly bimetallic, except that the inner and outer core compositions are reversed on the 1-euro coin so as to make the coins easily distinguishable from one another. The 2-euro coin is slightly smaller in size and slightly lighter than the 50-euro cent coin. In relation to the size of U.S. coinage, the 2-euro coin is slightly larger and thicker than the U.S. quarter dollar.
The 2-euro coin has an approximate value of $2.25 USD.

The Austrian Mint strikes the two euro coin in three unique finishes: a business strike intended for general circulation; a satin finish specimen strike produced for collector sets; and proofs, which are sold in annual proof sets. For the years 2005, 2007, 2009, and 2012, the Austrian Mint struck 2 Euro coins with commemorative national sides.
