(Christian Science Monitor) Here is an article noting that the U.S. Treasury would save $147 million by switching its $1 note with a $1 coin, but that proposal faces opposition not only from the supplier of paper, but also from a majority of Americans.
From a Swedish perspective, changing to a $1 coin would seem natural considering that here the highest valued coin, the 10 krona coin, is worth more, roughly $1.5, 6 times more that of the highest valued U.S. coin and 1.5 times more than a $1 coin would be worth
Still, even stranger from a Swedish perspective is however the coins that are still around, especially the penny. The lowest valued coin here is the 1 krona coin, whose value is about 15 cents, 1.5 times more than the value of the dime , 3 times more than the value of the nickel and 15 times higher the value of the penny.
