There are a lot of countries that use the dollar, the total amount of territories and countries using it in total I could find are 76 of them in all. There could be more than that, but that's for a future update. The Afghani currency is only used by Afghanistan, dongs are used by Vietnam, and the ouguiyas are used by Mauritiana, and well, in a very unexpecting place, Western Sahara! Western Sahara refuses to use the Moroccan dirham for currency probably.
