Coin production techniques and machines

[Figleaf]

A final note on the story. It is quite euro-centric. I thought about incorporating Indian hammering and Chinese casting techniques, but feared I didn't know enough about it. I just touched on main developments, going into detail only in the juicy case of Marx Schwab. There is much, much more to say about minting, but I wasn't out to write a magazine article.

The thread gives the impression that almost all inventions were made after say 1780. However, you can easily see from the coins shown on this site that the difference in artistry and execution between early medieval coins and late renaissance coins is enormous. The developments just weren't in machinery.

Please add to this thread as you see fit. I have followed a loose chronological order, but any order will do just fine. Thanks to AJG who contributed already.

A small adddition. In conductng my research I found the Royal Mint(UK)  used a canneluring machine to produce the edge markings on Maria Theresa thalers.  Up to the point of finding this out I had always associated canneluring machines with rifle ammunition.

Dear Figleaf,

  We have all seen pictures of old minting techniques, of course, but I have never seen such a complete description so well explained  or with so many good illustrations of the development of the process itself.  Many thanks for this useful and interesting set of posts.

   Well done, and keep up the good work.

I couldn't resist adding an advertising medal with a splendid knuckle lever coin press from the collection of capnbirdseye. The whole medal is presented here

I believe there are two different metals/dates of this medal. I have spent quite a bit of time staring at the machine on the "today" side. It may be a planchet cutting machine. Not sure, though.

Hmm, why did that look familiar to me? Ah yes. Voilà, the Dutch language version:

Yes, that is a coin press as Malcolm shows in his picture Epa916.jpg above. Note that there are 25 years between the French and the Dutch version.
