You have just found a euro and there is an owl on the back and it says eypo Where is it from?

All euro-denominated coins are issued by the European Central Bank. They are actually minted in various national mints. The Greek coin you describe was probably minted in Finland.

The euro coins have a common design on the reverse, and a country-specific design on the obverse. The 1-euro coin with the owl actually shows a 2500 year old Greek coin which had the owl design on it. eypo (or close) is the Word for euro in the Greek alphabet (y = upsilon or u, p = rho or r).

All of the euro coins are valid in any other euro country. Ones from the less populous countries like Malta and San Marino are hard to get and much sought after.
