We have had 1$ and 2$ dollar coins in Canada for a long time and hopefully soon we will get the 5$ coins soon. I really like the coins myself. If you are the kind of guyb who prefers buried money in your garden to stocks dollar coins rock. Coins stay in circulation 7 to 10 times as long so if you bury some you are not stuck trying to get rid of a bunch of old bills. They also make saving for things way easier. If you put all your change towards say the next Scrapper it will add up very fast and rather painlessly. I would say about 90% of people much prefer the Loonies(our dollar coin has a loon on it)to the old bills. It is also way cheaper for the mint.
It is not like they removed the "in God We Trust" just moved it.
You feel like a pirate with your "booty" when you have a bunch of coins.
