Re: [Error Coin Information Exchange] Re: Mystery Minting Machine - Fred W. & Mike D. please?

Mike,

Thank you for taking a look at the mysterious minting machine. As you saw in my text on that page, I too, at first thought it was an upsetting mill. However, this conclusion almost certainly is incorrect because the coins that are coming out of the machine are already struck! In fact, the coins in all three bags are all struck! Is there any way this could maybe be an edge-imparting device of some sort? The very first guess I received was from someone who thought it was applying the reeded edges. Of course, I smiled at this and moved on, but now I wonder…another one of my readers who claims to be an expert in minting says it looks similar to a Castaing edge lettering machine.

Is there any way, in your knowledge of these things, that this machine could be applying reeding or edge lettering? Particularly raised edge lettering?

Susan

In thinking more about the mechanism, it seems to me that one of the
plates holding the blank must move inward as the blank is moved back
and forth in the slot. That would create the rolling and squeezing
process necessary for generating a proto-rim.
