What do you do with the money you save in a jar?

We have a jar that we save change in. Id like to save it up for a great vacation or even something as small as a date night. My question is when you have a jar of change how do you turn that into something you can use? Do you take it to a coin star and lose 7 cents per dollar? Or do you change it somewhere else? do you put it in the bank? Or just spend the change?
