Today on the show: The penny. And the strange spot it occupies in our economy. It’s worth almost nothing, but not quite. We have three stories on the penny. First, we go on an expedition through the streets of Manhattan to find something, anything, we can buy for one cent. Next, we talk to a guy who’s betting on the government killing the penny. And finally, we visit a place where people dream of how pennies could change everything: the internet.
