I remember back around 1999-2000, there was a major PR push to start using the golden Sacajawea dollars. (featuring Michael Keaton as the voice of George Washington) [image=http://media.treehugger.com/assets/images/2011/10/US2520one2520dollar2520coin.jpg] Unfortunately it was a monumental failure. Supposedly there was a huge backlash from Coca Cola and Pepsi about the necessity of adapting vending machines to accept the coins, which would have cost them an estimated $50 per machine. "Big Soda" decided it was too expensive and attempted to get the government to shoulder part of the cost, but were shot down. I had heard of one story where a woman getting change at our local grocery store and threw a fit when handed a dollar coin as change, demanding "real" money. And then there is the governmental factor...one of the pushes for the coin was to replace paper dollars and save taxpayers a nice chunk of change. Unfortunately the government never so much as slowed down production of paper bills, making the coins completely extraneous. President Obama officially ended the dollar coin program in December. No new coins will enter circulation, and limited runs will be minted for collectors. Not even the $1.4 Billion worth of coins currently being held by the Federal Reserve. So, have you ever used a dollar coin? Or did you just take it to the bank and get paper? And do you know of any vending machines/parking meters/etc. that actually accept dollar coins?
