Franky I'd like to see the $1 bill removed from circulation, and issue the $2 bill instead. Roll out the $1 coins back into circulation to make change needed by a $1 device.
That way if you get change you can still make odd amounts, get those $1 coins back in use without people complaining about getting $4 in coin when they buy a small item with a $5.
No arguement here...other than the Father of our Great Nation belongs on our currency. From a pure math perspective, and if we are to believe wikiAnswers...
==========
The cost varies a bit depending on the market for its component metals - mostly copper, but with manganese, zinc, and nickel to give it that golden color. In the last couple of years the price has averaged about 14 to 16 cents per coin.
That price is one reason cited in favor of replacing $1 bills entirely. An individual bill costs less to print (around 6 or 7 cents) but $1 bills wear out so quickly compared to coins - < 2 years for a bill vs. 30+ years for a coin - that the life-cycle cost of a bill is far higher.

So yeah, it makes no sense to keep making one dollar bils...except that people want them. And truthfully, the dollar coins get ugly early. Really quick tarnish with not a whole lot of usage. If you don't mind lugging around a coin that looks like dull bronze...you're good.
