How to cast a metal coin the easy way


In this tutorial I show you how to cast a metal coin and how to make the rubber molds for it so you can make lots of copies. I would say you could get skyrim rich! I cast the Septim from skyrim.

You can also watch the video tutorial on how to do this. It is at the bottom of this page.

Coins are typically stamped but you can cast them with a low melting metal like bismuth. I show you how and in this tutorial I cast a coin called a Septim from the video game Skyrim.

The coin we cast


There are a few different ways to cast a metal coin. In this tutorial I show you a straight forward way to make a mold so you can make copies of the coin. And I also have a youtube video on this project. You can watch it at the bottom of this page.

What you need:

Here is a quick overview of how to make do this:

  1. Carve the coin out of a clay that hardens enough to be molded
  2. Cast 1 side of the coin in rubber
  3. Cast the 2nd side of the coin in rubber
  4. Those two halves make a rubber mold
  5. Cast metal into the rubber mold


Cut a tube

I created a little mold to press the clay into. It is just a cut piece of paper towel tube.









Mix the clayI mix together two parts of procreate clay. This gives us 2 hours of working time. At about two hours the clay is hard and cannot be worked anymore. This gives us a good solid coin to cast.

You don't necessarily have to use a hardening clay for this. It just makes it easier because there is less risk of distorting or bending it. You can use a regular clay, you just have to handle it very carefully.




Press clay into mold

Press the clay into the tube to make the shape.









Sculpt the coin

Next go ahead and sculpt the image of the coin.









Sculpt other side

Once you are done, flip it over and carve the other side of the coin. You can see here that it is placed on wax paper. That helps a lot with sticking to the table.







Make a boxNow we are going to make a rubber mold of the coin. Build a little cardboard box around the coin. There should be a little bit of extra room all the way around the coin.









Embed coin in boxPut about an inch of clay in the bottom of the box. Put the coin right on top of that then put a little bit of clay around the edge of the coin. Make it so the coin is about half embedded in the clay.
