Turning a coin into a ring is a great way to add a unique and personal touch to your jewelry collection. It’s also a fun and creative project that anyone can do with a few simple tools. To get started, you’ll need a coin, a ring mandrel, a hammer, a file, and a marker. First, use the marker to draw a line around the circumference of the coin. This will be the size of the ring. Next, use the file to remove any sharp edges from the coin. Once the edges are smooth, place the coin on the ring mandrel and use the hammer to gently tap the coin until it takes the shape of the mandrel. Be sure to tap evenly around the circumference of the coin to ensure the ring is even. Finally, use the file to smooth out any rough edges and to make sure the ring is the right size. Once you’re happy with the shape and size of the ring, you can add a bit of polish to make it shine. And that’s it! With a few simple tools and a bit of patience, you can turn a coin into a beautiful and unique ring.
