You've put together a challenge coin display you can be proud of... Now where should you put it? Through the years, you've earned a formidable collection of challenge coins. While they're beautiful, the real value of these coins is the powerful memories they evoke. You see that one? That's the one your commanding general have you when you earned an Army Commendation Award. That other one over there? They gave you that when you joined your unit in Afghanistan for your first tour.
