Easy Method To Make 3 Coin-Rings In 3 Hours For Hibernating Treasure Hunters :biggrin:

[John-Edmonton]

Save those Bi-metallic coins you dig up. They make coin-ring crafting so easy! Just pop those centers out and use the outside rounds to make a perfect ring. No burring required. The centers can be holed and used as jewelry such as earrings.

Slip those rounds on a ring mandrel or round tapered pinch bar. Hammer the heck out of them while pushing them down the mandril. The idea is to get them down far enough to eliminate the cone shape that you started with. Please anneal the rounds prior to hammering them down the mandrel to make them softer and easier to work with. When you have the shape you want, get some silver compound polish and use some felt polish bits on your rotary tool to put a nice finish on those coin-rings. 3 hours for 3 coin-rings from start to finish.

I have a Mexico coin I thought I would try this on but not sure what type of metal it is. Don't you anneal certain metals differently?

I still don't understand how you get the centres out? Maybe you could explain.

At first glance, i would chuck the coin up in in my lathe then either drill or use a boring bar (depending on the coin's dia. or drill bit availability) to cut the center out perfectly.

The OPer shows only a dremel tool, no other machines. Using a dremel tool to cut out the center, IMO would be the hard, labor intensive, tricky method.

I set the coin on an iron vise that was open enough that only the edges of the coin were holding it. I than took a bolt that was a little smaller dia. than the center hole and punched it out with a hammer. It came out real easy.

Set the coin on a holed piece of wood to allow the center to fall through. Set a bolt on the center piece and give it a whack with a hammer. It should pop out quite easily.

To anneal the coin, heat it up until it turns pink, then quench it in water or let it cool off.
