Math Puzzle 2 – Change for a Dollar?

It is a lazy and hot Saturday morning in the summer, in case if you need something to exercise your brain without any sweat, here is an interesting problem to solve.

A customer walked into a small local store, customer asked:

“Good morning.  Can you please give me change for a dollar?”

Cashier smiled, looked at her cash register, and reluctantly shakes her head:

“I’m so sorry, but I can’t do it with the coins I have here.”

“Oh I understand.  Can you change a half dollar instead?”

Cashier looked at her cash register again, scratched her head and said:

“Nope, so sorry.  I couldn’t even make change for a quarter, dime, or nickel.”

Customer is a bit desperate now, and asked:

“Do you have any coins at all?”

Cashier looked up and smiled, responded happily:

“Oh yes.  I have plenty, I have a total of \$1.15 in coins.”

Now the customer is quite confused, how can that be possible? Can you help to solve this mystery? Exactly what combination of coins are in the cash register?
