The most I rolled was $27, :-P Never again.
Those were all the pennies that few old students that have graduated (ex roommates of friends) - all contained in a shoe box.
While stacking them up for rolling, I actually got a good pennies collection out of it, some 1920s ans 1930s and complete 1940s onward. Few years ago I caught my little one taking many of those pennies and putting it on the piggy bank (aaaarrrggghh).
For Canadian penny, 1967 has a special design, a dove, I guess it is to commemorate the centenial celebration of Canadian Confederation - wow, lot's of Cs!
Canada doesn't have Independence day (no fighting taken place in the making of the Canada as a country).
