Might be talking about the United States specifically. IIRC the constitution denies individual states the right to mint coin or issue bills of credit, that is a prerogative of the federal government.
When the Constitution was being drafted, all of the thirteen original states had their own currency, plus the Continental currency. It was a mess. A few years later, they set up the US dollar, US mint, and so forth.
