Is there anyone who knows a good reference book or technical papers on the RCM manufacturing process?

I'm not looking for basic stuff, but a reference with good level of technical information from the initial design up to the coin strike and the evolution with time.

Actually, I have very little formal reference when I'm talking about the Mint Process at my Local Club. So such a reference would be quite useful!

Thanks for your help!

Lots of literature available in the RCNA library, which you can access remotely. That said, you will not find anything on the production details of modern coins, as that is patented protected. What is available on modern coins was an article published in the CN Journal after the Winnipeg RCNA, authored by Henry Nienhuis. A small group toured the production plant at Winnipeg, and Henry wrote an excellent summary of the coin production process there.

If any of their technology is indeed "patented", you can look up the details of that patent online, where the technology is described. Patents are made public so other engineers and innovators can avoid copying them.

However, if they just use "secret" or "prioprietary" technology that is not patented, it's just that, a secret. We would have no way of knowing, until potentially that information gets released somehow. This is the most likely case, to mitigate counterfeiting.

Edit: I did a search for Canadian patents on the CIPO website, using the search phrase " Royal Canadian Mint". If you specify that phrase as specifically the applicant's name, you will get a few results. Opting to search any field will bring up several pages of results, though not all are relevant. So there are definitely some very specific things you can find out there, although I imagine still that quite a bit of what they do are internal trade secrets.

The patents to the process of manufacturing the twoonie available online have just a little to do with the current process. The Mint is so protective of the process that even the availability of Canadian blanks is very very very limited - to my knowledge, until today, only 10 couplets were allowed to leave the Mint officially. Two couplets are in Canada.
