Do you mean KOPECK? In the Russian alphabet the name would be spelled Kопейка.
Before the Soviet Union collapsed a number of countries used the kopeck as their rough equivalent of the cent or penny. Today it's used in Russia and Belarus.
Money from Russia (and the Soviet Union) is denominated in Roubles, each comprised of 100 kopeks. "Kopek" in the Cyrillic text of Russia, is written "КОПЕЕК". For further identification, "Russia" would appear as "РОССІА" and "USSR" (the abbreviation for the "Union of Soviet Socialist Republics") would appear as "СССР".
That is 'kopeck' in Russian (Cyrillic).
I believe your coin is from Bulgaria.
The coin usually has the name of the country or ruler on it.
That depends on which country the coin is from.
The Two Shilling (or Florin) coin is a British coin. British coins do not have the country name on them. The Two Shilling (or Florin) coin was also issued by a large number of British Empire/Commonwealth countries, but will have the country name on them somewhere.

Centenary of what? What country, what coin, what year?
There's no such thing as an "international coin".If you mean a coin from a country other than the US it's called a foreign coin in every country except the one that issued it.In any case you need to post a more specific question with the coin's denomination and the name of the country it came from.
Such a coin does not exist. Please check the date and country of origin of your coin.
