Because I only visit the U.S. once or twice a year, I'm always noticing things I might not otherwise. It's a big surprise to me whenever they change the U.S. money, for example redesigning the bills to add anti-counterfeiting features. This time I started receiving those new $1 coins, which feature different presidents printed on them and which have a nice gold color that makes you want to go out and buy a pirate's chest. Although most Americans no doubt like having the $1 unit in paper form, the fact is that governments spend millions to print these bills only to have them wear out in a few years, and it makes sense for the U.S. to follow Europe, Canada and Japan in retiring its lower-denomonation bills in favor of coins. Japan gave up its 100 and 500 yen paper notes long ago, with the main result being that if you have a pocketful of change you can probably buy half a tank of gas, and once you get used to the new money, it's not a nuisance at all. So I say, bring on the $1 (and eventually, $5) coins!
