Query: Not Happy

I am a teacher who was going to use this product for the money unit we are currently studying, I was very excited about this product because of how realistic the money looks and that it came in a great carrying case with a lid for easy storage. To my dismay there are no pennies, (I was provided with two set of quarters instead) also there is no lid included. I called the company and have yet to hear a response.
