Hi again REDWINE,
No, there are actualy quite a few, but they have suttle differences in design.
For example, the one you display at the start of this thread shows maple leaves on the reverse. Others such as the Belleville issue of 1838 show an open wreath on the reverse, and yet others with un sou show sixteen cherry leaves on the reverse.
All un sou examples come from Montreal, and there are other examples too numerous to mention here.
I am sure elsewhere on this forum there are links to help you understand better..
