I did not see any reply to your question...so I will try to clarify it:
In the Argentinian catalog (Author: Hector Carlos Janson) which is according to me the best reference we have in 1992 KM#109:
120.000.000 Chile - Fine numbers - 24 reeds/cm
60.000.000 Brasil - Fine numbers - 24 reeds/cm
50.000.000 Canada - Fine numbers - 24 reeds/cm
He says that we cannot make the difference for Chile & Brasil because they used the same matrix (cunos(sp), coin (fr)) and for the Canadian ones, they are darker and the rim is bigger (Las canadienses son de color mas oscuro y su reborde es mas grueso)
So Numista lines are not exactly correct; they added the 2 first ones: OK but it is for Chile & Brasil (not only Chile) and comments are inverted: Canadian are darker and with a broad rim.
