Behold:

Sens. Tom Harkin (D., Iowa), John McCain (R., Ariz.) and two colleagues Tuesday are introducing legislation that would kill off the dollar bill in favor of dollar coins, touting the move as a way to cut costs over the long run.

“Promoting the dollar coin is a smart investment for our country that saves taxpayer’s money,” Harkin said.

Will this spell the end of the gambler's roll? (Brendan Kiley explained to me that a gambler's roll is the opposite of the traveler's roll—I sadly only knew the gambler's roll from its racist name, which I picked up at my British standard all-boys school. It has always surprised and embarrassed me how colonial-era antisemitism was so easily adopted by black Africans.)
