What are the Sharia-compliant regulations for issuing currency?

There are no specific Sharia regulations for issuing currency, but the Sharia came to bring about benefits and avert harms. The extreme need of people for currency necessitates that it be issued by a responsible authority capable of fulfilling its value and minting coins that are difficult to counterfeit. The rule of averting harms also dictates against tampering with currency due to the damages it causes.
