Doc,
It would be easy enough to put a page on the site for the coins. I can add a form (like the one I did for the reunion) that someone could fill out and submit to place an order. I can have the form send two copies, one to you and one to the person ordering with instructions to print it out and pop it in the mail with a check or money order....
Hell... I could even add a private page to my ecommerce and we could sell these completely online...
All kinds of options.... easy to implement...
