Does it circulate?

I was wondering if the commemorative-sized Polish 2 zloty coin is actually circulated. Is it used alongside the bimetallic kind of coin? Which one is more often seen?

Anyway, feel free to use this thread to ask our international members how much a particular coin actually circulates - this is one piece of information I am always wondering about, but sadly it is hard to put in a catalog. I'll answer ahead of time: the Canadian 50-cent coin is hardly ever seen and can nowadays only be purchased from the Royal Canadian Mint at a ridiculous cost of $1 each!
