Careful throwing too many of those 'defactos' at me at one time, I'm just a piney woods boy and I get real confused! You can tell cuz' we spell cypress like the trees! (I misspelled it several times in my post)

Kidding aside, Excellent question!

There is only one Cyprus pound, drawn on the Central Bank of Cyprus and used by the Republic of Cyprus.

TRNC (Turkish Republic of Northern Cyprus) uses the same currency as Turkey, the Turkish Lira. Example shown below.

The currency is exchanged just as it is between the Republic of Cyprus and Turkey between the two nations (GRC and TRNC).

The UN has held numerous discussions from 1985-92 without any results towards unification. So it appears this is how it will be for some time to come.

Sorry, I was so late seeing your question.
