There are a few ways you can do it. Go to a bank and ask if they have any halves on hand. If they do buy them all. You can also have your bank order you boxes from the fed reserve but you have to order them in 500.00 increments. Not all banks order coins so you have to find the ones that do. From what I have been reading there are also casinos that have halves. Im not quite sure what thats all about since this state doesn't allow gambling. :P
