Nickeled and Pennied
The movement is growing to eliminate the penny, which actually costs 26 percent more to produce than it's worth. See, for example, Stephen Dubner's post over at Freakonomics.
I have no sentiment allegiance to the penny, so I'm fine with losing it. But what about some anti-love for the nickel, which costs a whopping 54 percent more to produce than it's worth!?!
When I can, I pay with plastic. Now, not everyone has that luxury, or wants to; but it would seem to me that not having access to nickels and pennies would be a small price to pay so that the US government doesn't lose money every time it makes them.
