Dollar Coins

As if the US wasn't trying to confuse foreign tourists enough with the 50 state quarters, now we get to add another variation on the dollar coin to our currency mix. Instead of Sacagawea, now 4 dollar coins per year will feature Presidents of the United States on the back. Sounds great, right? Makes you want to start using dollar coins, doesn't it? Interestingly the last President planned for this program is Richard Nixon. Why stop at Nixon? Aren't Ford, Carter, Reagan, Bush and Clinton worthy of this program as well? If Watergate isn't enough to prevent you from having a dollar coin, what is? Also, by the time their quarters would be available it will be 2016, 30 years since Reagan was in office. That should be enough time, right? Another fun fact, Grover Cleveland will get 2 coins for his 2 nonconsecutive terms. I don't know if I can wait until 2014 to get my Warren Harding coins!
