What was the first your US currency?

The first U.S. currency was the Continental Dollar, issued by the Continental Congress in 1775 to fund the Revolutionary War. These notes were backed by the promise of future tax revenues but quickly depreciated due to lack of backing and rampant counterfeiting. The first official U.S. coins were minted in 1792 with the Coinage Act, leading to the creation of the U.S. dollar as a standardized currency.
