Making Lemons into Limonada

mxUnPesoCoin_cracked_logoI started to make a coin ring out of a 1958 Peso. As you can see from the photo to the left, things did not turn out as expected. The peso coin from 1957-1967 is 10% fine silver and 70% copper and 10% Zinc and Nickel. So I was a bit surprised with it cracked while I was stretching it. This combination seems somewhat brittle.

mxUnPesoCoinAfter I felt the tell-tale “give” on my ring stretcher, indicating the appearance of the crack, I quickly became somewhat discouraged. Then I had an idea. When I choose the hole punch size, I did so with a mind to preserve the eagle devouring the snake at the center of the reverse side. It’s such a cool symbol that I thought I would do something special with it. so with the center portion intact, I formulated a plan.

I continued to form the broken ring using the Swedish Wrap Technique created by Mikael Möller, with Jason’s amazing tools from This allowed me to get the broken cone shaped into a ring shape. It worked like a charm, though I could only reduce, not enlarge.

mxUnPesoCoin_cracked_shaped_logoAfter I got the ring formed, I was ready to grind and solder. I ground the area at the crack flat, then filled it with a little solder. (It was already a pretty good fit…the photo exaggerates the mis-alignment.) Then I ground the surface of the plug that was to fit against the ring.

mxUnPesoRing_inside_logoI have to admit, soldering the two together was a little more challenging than I expected, but I finally got the two parts soldered together. In the end, I think I came up with a solution that really works. It turns out that the finished ring might be better because of the accident.
