Coin rings are a great way to repurpose old coins and create a unique piece of jewelry. Making a coin ring from US coins is a fun and easy project that anyone can do. All you need is a few basic tools and a bit of patience. To make a coin ring from US coins, you will need a few supplies: a coin, a ring mandrel, a hammer, a drill, a file, and a marker. Start by selecting a coin that you would like to use. Make sure that the coin is in good condition and that it is not too worn. Next, place the coin on the ring mandrel and use the marker to mark the size of the ring that you would like to make. Use the drill to make a hole in the center of the coin. This will make it easier to shape the coin into a ring. Once the hole is drilled, use the hammer to shape the coin into a ring. Start by gently tapping the edges of the coin until it is the desired size. Then, use the file to smooth out any rough edges. Finally, use the ring mandrel to make sure that the ring is the correct size. If it is too small, use the hammer to gently tap the edges until it is the desired size. Congratulations! You have now made a unique coin ring from US coins. This is a great way to repurpose old coins and create a unique piece of jewelry. Enjoy your new coin ring!
