Change in Change?

Is it just me, or has everyone noticed a lot more American change in their pockets these days? I have received three quarters, two dimes, and one nickel of Amercian change from various Montreal vendors this week.

Now, I know that when you look for something, you notice it more. But for those of you that know me I'm a bit of a coin and note fanatic: generally, I look at the change when I get it back (for commemorative or rare coins, not to see if I'm being short changed). So, maybe this isn't a coincidence. I guess people are just starting to get rid of those American coins, realizing they are worth less than their Canadian counterparts.

Food for thought.
