Absolutely. Canada has done it successfully for years, replacing both the 1 and the 2 dollar bill with coins. The US needs to get serious by finally supporting the decision by retrofitting so many automatic machines that take coins so they can actually be used in every day life.

Not a good idea for me,my pants would fall down with all that weight needed in coins to pay for just everyday expenses.

Canada -- Germany - UK -- all have had coins and have survived -- It saves a lot of money -- and many have a small leather holder for carrying them

We all know it makes sense, and we've tried this before with the Susan B Anthony coins. Unfortunately, it never took off and I still have a few. What will be different this time?

So, over 30 years, $4.4B would be "saved". Does this mean actual outlays to the tune of about $144Million per year (if I did the math right) would be eliminated by the federal government and returned to the taxpayers ( based on 300 million people in the US, a whopping $2+ per year per person on average?). I am a bit cynical by nature, but I doubt whether any money would actually be saved. Yes, Canada has the dollar coin, I go there a lot and it is a pain to carry. $10 as 10 coins is a lot more bulky and weighty than $10 in paper.
Even if the savings would be realized, they are so small and insignificant I wonder why anyone in the government thinks it is a good use of time to even consider the effort. Although, I suppose it is easier than proposing shutting down some useless government organization (Dept of Energy for one).

Well, that would make visiting Providence MUCH more interesting.
