Yes, It looks it, but I do not know much. Also, I found a few hanging threes in a total of around 260 1963 UNC Canada cents I found in a penny box.
I find a Canadian cent in roughly 1 out of 10 rolls. I have yet to find one of these clashes. I like 'em!
these also have 3 dots on number 6,, 2 inside and one above,,i found 18 of these I think they are pretty cool
