Its a challenge coin.
Its a military thing.
You have to have one on you at all times.
If somebody shows theirs and you don't have yours
Then you owe them a drink.
But if they challenge you and you produce yours
They owe you a drink
Didn't that seem forced?
Like Miller was nervous to say it?
Pence was calm
Miller not so much
Some collect them
But I was wondering if it were a marker given in that context
Something he can cash in at some later date
Maybe an appointment to a post somewhere
