Question

Timothy, a cashier, is given a twenty-dollar bill at his store. He is suspicious of the customer and wants to make sure the currency is real. Which would be a clue that the currency is counterfeit?

Answer 1

He could see if its made of cotton or paper ( real money is made of cotton), or see if the serial number looks kind of odd

Answer 2

There is no color change on the bill. There should also be watermarks on the bill along with a security thread in all bills over a $5 note.
