For starters, I never really thought about this until I moved overseas. Now, I’m living in the UK and hope the US never switches to dollar coins exclusively. Why? Well, here, we have 1 and 2 pound coins and no bills. The smallest bill is a 5 pound note. I can pay for a purchase with a tenner (10 pound note) and get nothing but coins. And they weight a ton.
I hate it and i think most americans would too. This is a horrible idea.
[Update 2011-03-11 18:40:52] Here’s another article talking about how people in the US dislike dollar coins. After using 1 and 2 pound coins, I am one of the one’s who would vote no one dollar coins.
