"The cost to taxpayers in 2008 alone was $848 million, more than two-thirds of which was spent minting coins that many people regard as a nuisance.

In an era when books, movies, music, and newsprint are transmuting from atoms to bits, money remains irritatingly analog. Physical currency is a bulky, germ-smeared, carbon-intensive, expensive medium of exchange. Let's dump it."
