To borrow money is a concurrent power. This means that the power is shared by both the State and the federal government, and is exercised simultaneously.
In the US government, the power of coining money is delegated or expressed.

Concurrent Powers
Okay, first of all, it isn't even a delegated power. It's a concurrent power; meaning both the states and the national government can collect taxes. I guess it's because we need money in order to function as a country, so taxes are collected.
Delegated power is power specifically outlined in the Constitution. These are in contrast to implied powers which are not outlined.
No, it's an expressed power of Congress and could not be delegated.
Delegated powers can do whatever falls within the scope of their power itself. For example, if my delegated power is education, then this power gives me the ability to do anything within the sphere of education in my political jurisdiction.
