It is a little difficult to make out, but the word is "pingin", Irish for Penny. Punt is the Irish word for used for the currency in Ireland prior to the Euro, and would be seen on The £1 coin.
It would be a real coin. Éire is the official name for Ireland in the Irish language, so it is a coin from Ireland.
Éire is the official name of Ireland in the Irish language. It has not used the punt as its currency since the introduction of the Euro in 2002.
Several countries use (or used) the franc as their currency. Please post a new question with the coin's country of origin. Note: If it says "Confederatio Helvetica" your coin is from Switzerland.
Eire is the Irish term for Ireland. The harp is the historical symbol of Ireland and has been used on Irish (Hibernia, Eireann, Eire) coins for hundreds of years. 1d indicates One Penny (or Pingin in Irish), the "d" dating back to Roman times being derived from the Roman coin "Dinari". This was the symbol used by Britain and most British Empire/Commonwealth countries to indicate a "penny" value. The reverse of the Penny shows a chicken with chicks. The reverse of all pre-Euro Irish coins feature fauna from the Irish countryside. The Irish Pounds, Shillings and Pence currency which was based on the long established British currency, was discontinued and the currency progressively withdrawn in favour of a decimal currency based on 100 Pence to the Pound in 1971.
There's no coin called a "frank". The FRANC is a denomination used in Switzerland and was used in several other European countries until 2002, as well as former French colonies in Africa. Because of that much more information is needed. Please post a new and separate question with the coin's date and the name of the country that issued it. If it says "Helvetia", that means it's from Switzerland.
The lettering on the coin is almost certainly in the Cyrillic alphabet used in Russia and some other Slavic countries. "ру́бль" means "ruble" which is Russia's main unit of currency so your coin is most likely from that country. The ruble trades at roughly 30 to the US dollar so a 1 ruble coin would be worth around 3 cents.
Officially the name is Éire which appears on Irish coins and stamps. In English, that is Ireland. The term Republic of Ireland is commonly used, but it is not the official name of the country.
Greece used the Drachma before 2002. Since then it uses the Euro.
who trust the lord shall not be moved. you have a 1640 lion coin. they are from the netherlands and were heavaly counterfited and circulated and were even used in the US colonies.
Please post a new question with the coin's country of origin. England has never used cents, only pence, so if you have a coin with no country but a denomination of 3 pence it's British. If it's from another country it should have the name somewhere on the coin.
The drachma was a form of Greek currency, so the answer to your question would be Greece.
