I have a question and I hope someone can answer it for me. When I take loose or rolled change to a my credit union how can they charge me a fee of up to 10% for the exchange. They dont charge me if I have 100 1$ bill and ask for 2 50$ but if I have 100 dimes they want to charge me 10% for having to count the change. I don't understand how this is legal since I am exchanging legal US currency of one type for another. If anyone has any information as to how they (credit unions and banks) can legaly do this I would love to know. If anyone know's of any rules stating that they can't do this I would be doubly appreciative.
