On coins and Canada they have a 1991 listed as a "Double date" that looks similar to the example shown in this post but lacks the needed photos in order to determine if it is the result of the same issue as mine since the example I have is in the opposite direction and has a lot more questionable areas on the reverse.
I just thought I would share this one, it is not often you find 91's with
Machine Doubling this severe.
