It would take senior CF support to get a general currency special coin minted. And definitely need the Infantry Advisor and PPCLI Col Cmdt to get the Comd CA on board for starters. Now making your own coin is much easier, I'm in the process of making trade coins for all the EME trades with a few other motivated members of the EME branch. And while some amount of work on the logistics of it, getting base reps, numbers and collecting money etc, it is relatively easy to to accomplish as it doesn't require any high level approval. Unless you want unit or branch funds, but if you operate on a cost recovery it's not hard.
