The editorial writers at the Chron can't seem to understand why the Sacagawea dollar coin has been a flop, much like the Susan B. Anthony coin was years ago. It's no mystery to me, y'all. Why carry heavy coins in your pocket where they can fall out when you can carry nice thin dollar bills in your wallet? Vending machines have bill readers in them nowadays and most toll roads have some form of EZPass electronic payment system, so for the most part there's no real need for dollar coins. I understand the government's economic reasons for preferring coins, but I'll take a greenback any old day.
