Yet Another Reason to Hate the Penny?

Readers of this blog may recall Dubner’s crusade against the penny due to opportunity cost as well as the high actual cost of producing pennies. Now Slate takes a look at another currency question: is cash or credit more environmentally friendly? The article doesn’t manage to answer the question, but it does point out the heavy environmental toll of producing coins. More support for Dubner’s theory! And if you’re looking for a really compelling argument against coins, consider the possibility that coin-flipping isn’t as kosher a means of settling a bet as you might think.
