I didn't really plan on making and Instructable for these but I had enough video I figured I might as well. You will need pewter and either a steady hand for carving or a cnc machine. Gloves and safety glasses are also a good idea. If you want to see the video on YouTube check it out here.

Step 1: The Heads Side

This side is carved down into your piece of wood, I used a diameter of 3" and made it 3/8" deep with a rim around the outside at an additional 1/16" deep. The head image is .1" deep and pocketed out with a tapered endmill. A straight mill will work it will just be harder to get apart. I cut a gate leading into the coin at the very bottom, this is where you will pour your pewter. It is roughly 1/4" wide where it meets the coin and 1/2 at the top.

Step 2: The Tails Side

The tails side of the coin has everything around it cut away so the coin portion sticks up 1/4". Make the diameter of this slightly smaller than your your Heads side, I did mine at 2.9". Again the image is cut down in .1" deep and there is a 1/16" deep rim around the outside that is roughly 1/16" wide.

Step 3: Melting and Pouring

Pewter melts at 400°F so you can melt it pretty easily. I just throw mine in the woodstove for a few minutes and it's ready. You can use a steel can from some some vegetables for a crucible. Pour this into the gate at the bottom of the coin until you see it start to fill up past the depth of the coin.

Step 4: Finishing

After your coin has cooled you can take apart your mold. If you do this too soon your coin will be very fragile and break before you can get it out. After you have your coin out you can cut off the extra with any woodworking saw and sand it smooth on the rim. I used 220 sand paper for this. I also did a quick spray with black spray paint and polished the faces and outside rim of the coin with 220 sand paper after the paint was dry.
