If anyone who is still breathing has not seen the movie Tombstone this may come as a surprise, but you can, indeed, roll a coin down the knuckles of your hand. It's very simple to learn, but takes a bit of patience and practice. This instructable will teach you how to do it.
Okay, so I really don't know if the real Doc Holliday ever actually rolled a coin across his knuckles while playing high-stakes poker, but it could have happened, right? Frankly, who cares? Val Kilmer did it while portraying Mr. Holliday in the movie and it has been cool ever since. It may have been cool before, but things only get cooler after a movie star portraying a quick-drawing, intelligent, articulate, irreverent, hard-drinking, heavy gambling, and yet very sick gun fighter does it on the silver screen.
This is not a terribly easy thing to describe in the written word alone so I have included a brief video of me performing the feat somewhat poorly, though passably. But don't forget the Tombstone video either, as Val does a great job! I apologize in advance for my ineptitude. In my defense, however, I used to do this much better, but simply fell out of practice. So now I can't do it well. Add that to a growing list of things I used to be able to do and let's start!
(And yes, I know I need lotion. It's cold in Indiana right now.)
Step 1: Choosing a Coin
The first step is choosing a coin. The coin size is important, as you will find out. Too big or too small of a coin will not roll the correct way over your knuckles. This is going to be an individual decision as we don't all have the same size fingers. I find that an American half dollar works for me. You may need something a little smaller or a little larger. Experiment. If you can't find something in your own nation's currency you can always try something from a different country. Coin value makes no difference as people will be mesmerized more by your technique than the fact that you are in possession of a Golden dollar or whatever else you may procure (unless you are spending time with numismatics).
