If you are paying attention to such things, the standard 3 inch jumbo coins are available in nearly every coin out there... EXCEPT walking liberty halves.

I use WL coins for my routines. I think they are the most beautiful coins that the US Government has issued. So to have found a source for 3 inch jumbo halves, makes me very happy indeed. If you use these beautiful coins for your coin work, you may want to have a few of these jumbo, hard to find utility props in your back up supply.

They are $6 each.
