These notes will include all current as well as former countries belonging to the continent of Africa. For example, I have a banknote from Zaire, which is no longer a country. Also, not all of the currency is still used as a current medium of exchange. Zimbabwe is a good example of this. My 100 Trillion Dollar Zimbabwe note was printed during the country's hyperinflation period. The country no longer uses the Zimbabwe dollar and now has virtually no value except to collectors like myself.
