Your logic is flawed. You argue no nation uses two currencies ONLY to offer examples where more than one currency is used. if two currencies are being used, and can be used, why not three or five? Damiinimadu waa ibtilo rabbaani ah! Did you know there are nations where up to 4 currencies, or even more, are being used? Let me catch you up, as you seem a bit behind the curve: PL is going one step farther to Confederacy to rein in the tawdry Centrists (Kacaanists), which is the only way to tutor the dimwits. Did you know PL already has its own SOS only used in PL? Did you know SOS used in Xamar is not accepted, nor works in PL? It is where the old Arab Bard opined: إِن كانَ سَرَّكُمُ ما قالَ حاسِدُنا فَما لِجُرحٍ إِذا أَرضاكُمُ أَلَمُ Scotland & Ireland have their own currencies, minted by Banks of Scotland & Ireland, distinct from England & Wales. Both are accepted elsewhere in mainland Britain as codified in the Acts of Union. Noteworthy, in Scotland & Ireland, one would find one pound note, yet so is not true in England & Wales. Nations where more than one currency is used: Serbia-Montenegro (Yugoslav dinar & € ), El Salvador (peso, bitcoin, $), Panama (balboa & $), Cambodia (riel & $) Amongst others, East timor, Ecaduaro use US $, Pacific islands use NZ $. There are nations where currencies of other nations are accepted, say Brunei & Singapore, S Africa rand accepted in Namibia & Lesotho etc. ------------------------------- List of countries where US $ is used: United States (American Samoa, Guam, Northern Mariana Islands, Puerto Rico, United States Virgin Islands), Bonaire, British Indian Ocean Territory, British Virgin Islands, Cambodia, East Timor, Ecuador, El Salvador, Liberia, Marshall Islands, Micronesia, Palau, Panama, Saba, Sint Eustatius, Turks and Caicos Islands, Venezuela, Zimbabwe
