Metal coins have a very long life, they generally get lost before they wear out. Whereas the one dollar bill is cheap to make, it lasts on average less than two weeks, so the banks have to keep on recycling them. This increases their equivalent production cost to be more than a 2 dollar coin would be, were there one.
In some countries, they take note of this and as inflation eats the value of money, they mint larger denomination coins and remove the lower value notes. The UK is now using 2 pound coins and has no one pound notes - although one pound is worth more than the dollar. The 2 euro is the largest coin (about US$3) and the 5 euro the smallest note, which one rarely sees, as they wear out too quickly, so one mostly sees 10s, 20s, and 50s.
I guess such a step is too radical for congress, replacing the one dollar note with a coin would be maybe just too unpopular. Steel coins are not unusual, the old German Pfennigs were steel with bronze faces, IIRC.
