Answer:
Coin.
Step-by-step explanation:
Thomas Jefferson was one of the many anti-federalists who held the belief that power should not be vested on a single person but on multiple people. He created and introduced the decimal-based currency system for the better exchange system for business or any transaction.
The type of money system that he designed and started was the coinage system or the use of the coin in any system of transaction. Thus, the correct answer is COIN.
