When was money first used in USA?
The first dollar coins were founded in 1792 by the united states mint.

Correction Prior to independence the colonies of course used whatever currency was available from the colonial powers, mostly British and Spanish coins.

The Continental Congress issued some of the first paper money in the newly-independent USA, but these quickly became worthless. The US Dollar was established as the nation's official currency by the Constitution of 1787. The Coinage Act of 1792 defined the specifications of the first silver coins including the dollar. The first circulating coins were 0.5 and 1 pieces dated 1793, and silver dollars were first struck (not "founded") in 1794.
