I had started this documentation a long time ago, but only today I saw, putting some doubles 1983 coins aside, that I never finished it. My problem is, I cannot remember where on internet I found the near side coin, I only have the same size macro as I had made of my own coin.

I'll still make a change request to have this documentation in the comments here:
