Just a little off topic. As cadets/midshipmen, or in the life after the academy as an officer, there is a good chance you will receive a coin or two. I'm not talking about buying coins. Different commands, especially flag/general officers will from time to time present service members with a coin, called "coining". There are also traditions of using coins to get free drinks in bars, but I've never been a part of that. Nice thing about a coin is it often has a story behind it, and for your "favorites" you'll remember that story when you look at it.
