On half dollars. I for one when I order a box or more, I never turn them back in the same bank or town. I use them for tips at restaurants. When I buy stuff, I use them also if the difference is 50 cents or larger. The clerks sometimes will not take them. I do this a lot when on vacation. Even had to buy gas once and got about forty dollars worth and paided it all in half dollars. Had to get the cashier to get the manager so they would accept them.
