Seal of approval
The government could apply its seal on metal ingots used by people in trades, to guarantee their quality and create units of standardized weights. That would facilitate exchanges and increase the people's trust in the currencies they're getting in exchange of their goods while giving us full control over the management of these special "coin" ingots.
