Which agency permission is required to a country to mint the quality notes ?

The correct answer is The Reserve Bank

The Reserve Bank is an entity responsible for managing a country's economic policy. It functions as a federal autarchy, that is, a legal entity that has its own functions and is linked to the State.

The Reserve Bank of each nation is considered "the bank of banks". It must guarantee the stability of the financial system and the purchasing power of the currency in force in the country, the Real. Purchasing power means the ability to purchase goods and services in a specific currency.
