Many coins can be made into rings for only a fraction of the cost of rings from a jeweller. Make your own coin ring by removing the centre of a coin, turning the coin inside out to leave only the ringed edge. Use half dollars for men's rings and quarters for women's rings. Pennies and dimes are ideal for children's rings. Prior to 1964, all quarters and half dollars were silver-based. For a silver-based coin ring, use a coin that was made before 1964.
Place the coin on a hard surface, holding it on its edge using your thumb and forefinger.
Tap the edges of the coin with a hammer to make it smaller in diameter. Turn the ring to tap all of the edges until the edges widen and the diameter gets smaller. This process takes between 10 and 15 minutes.
Drill a hole in the centre of the coin. The coin will jam onto the drill bit once the bit goes through the coin. Do not remove the coin from the drill bit.
Sand the edges smooth. Hold a piece of sandpaper against the edge of the coin and turn on the drill. Spin the edges of the coin against the sandpaper.
Clamp the coin between the rubber-tipped vice grips. Use rubber tips or wrap a cloth around the tips of metal grips so that the coin does not slip from the grips.
Use a Dremel with a cutting bit to remove the centre of the coin. Keep the coin tightly secured within the vice grips.
Turn off the Dremel and change the head to the sanding disc. Sand the inside of the coin smooth.
Change the head of the Dremel to the buffing wheel and buff the entire ring, inside and out, to a shine.
Buff your ring with metal polish such as Brasso.
Do not be hasty when hammering the edges of the coin to widen them. Work slowly and patiently to avoid distorting the ring.
