Very cool! The metal coins, are they hammer struck? If so, how many blows? I've only seen modern ones in silver, but I imagine harder metals like copper or brass might be a challenge. How do you make the planchets? I've seen some that are cut our of a band of metal which were thin, like some of yours appear to be. Very cool stuff!
These are not hammer struck, they are actually roll pressed. It's a similar method to how the Spanish pillar 8 reales were made. As for the planchets, a heavy duty sheet metal slicer, and 12-18 gauge metals. I normally use 14-16 for them, but I've used lots of scraps to make some, so they are really thin, some almost 22 gauge. The silver ones are actually struck over Engelhard rounds that were rolled smooth. The edges are either clipped, or clipped and hammered to give them a more traditional look. As for copper and brass being harder than silver? When it's annealed you can bend 16-18 gauge copper and brass in your hand like it's a hunk of thick wax. 14 Gauge and below you may need to use 2 hands lol. If you think I'm kidding, take an old english penny and get it red hot, quench it in water, and have at it.

I've had a lot of fun using these dies to make these coins, they are distorted, and nearly twice as big as what I started with because of the pressure, but still usable. I am trying to use them until they break, and make some with the broken dies just for kicks.

And I got some new additions today!


This ones two heads of 18th century (late 1760's-1780's ish) soldered together. I don't know why they used two different heads....or why they did it in the first place.




And I finally got a REAL 1910 Mexican peso, and for a great price, plus, check out that color!
