The trail even Sacagawea couldn't blaze

Think the third time will be the charm for the dollar coin in the U.S.? Refusing to concede defeat after the chilly reception to the Susan B. Anthony and the only slightly more enthusiastic uptake of the Sacagawea dollar, the mint is debuting yet another dollar coin today: the Presidential coin. Among the lures the Mint is dangling are "larger, more dramatic artwork" and edge inscriptions of "E Pluribus Unum" and "In God We Trust."

The New York Times has a detailed look at the dollar coin's advantages and travails. Personally, I like 'em. New Yorkers probably deal with more Sacagaweas than most Americas, since the subway machines give them as change. When I've gone and visited Australia (where David hails from), I've always adapted pretty quickly to the coins-only system for $1s and $2s. Although, their $1 coins have kangaroos. I bet $1 coins would be way more popular here if we put kangaroos on them.
