I picked up a shadow box from Michael's during a sale that holds pin on medals, awards as well flag holder.

It is a larger sized one but I have a few challenge coins from my time in the service so I figured lets get creative. All the options I saw online didn't really work for me so I made one that is custom fit for this box. I used earth quake putty or museum wax to secure the coins in the positions I liked.

If you print it, please upload a picture so I can get some ideas on how to improve my display case further - thanks in advance.
