You are asking about a 1994 50 Drachmes coin from Greece which commemorates the 150th anniversary of the Greek Constitution. What you are reading as "Eaahnikh Ahmokpatia" is actually the Greek words "ΕΛΛΗΝΙΚΗ ΔΕΜΟΚΡΑΤΙΑ" which are pronounced "(H)ellenik(eh) Democratia" and mean "(the) Greek Democracy".
According to the Standard Catalog of World Coins, there are two versions of the coin, each with a different portrait, although the back of each has an identical rendition of the Greek Paliament building. The version with a portrait of Dimitrios Kallergis (portrayed wearing a military uniform) is KM#164 and the version with Makrygiannis (portrayed wearing a turban) is KM#168. Each are brass and measure 27mm in diameter, and 7,500,000 of each version were minted. Each are worth about US$3.00 in Uncirculated condition, and US$5.00 in Brilliant Uncirculated condition.
