Basic Supplies

  • container of water, nail file
  • 1. Refer to photo for size chart and choose coin.


  • 2. Anneal coin using propane torch with tweezers. Take coin to a dull red in a darkened room and quench in cool water.
  • 3. Refer to photo for common hole sizes and band width of rings. Scribe circle in center of coin using dividers. Center scribed circle with die. Punch hole in center of coin using die and 2 lb brass hammer. Once hole is punched, check with dividers to make sure hole is perfectly centered. Remove irregularities with file or buffer. If using Self Centering Coin Punch, place coin in Self Centering Coin Punch with corresponding spacer, die, and punch. Use a two pound brass hammer to punch perfectly centered hole in coin.


  • 4. Refer to photo for a list of ball sizes to be used for different coin sizes. De-burr coin hole on both sides with a file. Anneal coin, center in reduction die, and place plastic bearing ball in coin hole. Carefully press down on plastic bearing ball, making sure coin stays centered. Once ball is pressed all the way down, anneal coin again and reinsert coin and slightly larger ball in die. Repeat process with slightly larger plastic bearing ball.


  • 5. Anneal ring. Stretch ring 2-4 sizes larger than desired size using ring stretcher/reducer. Anneal continually while stretching ring to prevent tears.
  • 6. Lightly file edges of ring's rim and apply lubricant. (Refer to photo for approximate die sizes for each coin type.) Place coin ring edge inside reduction die. Pull lever to push ring into die so it contracts in on itself, forming a ring shape. Anneal continually while reducing ring to prevent tears.


  • 7. Reduce ring to desired size.
  • 8. Add patina with liver of Sulfur following manufacturer's instruction. Darken ring to achieve dark patina.
  • 9. Polish high points of ring for contrast to show coin details. Remove any burrs or sharp edges using half round file, nail file, and buffing wheel. Use steel wool #000 to lightly polish inside of ring. Use polishing cloth for shiny luster. Apply polishing wax to seal the patina.
