$1 coins... and the Montana quarter

So the U.S. Mint is coming out with a new $1 coin. The Sacajawea coin was a bust. The Susan B. Anthony silver dollar was about the size of a quarter, and was often confused for one.

When I was in Japan a few years ago, I quickly learned that Japanese currency does not have a paper bill for their equivalent of our one-dollar or five-dollar bills. You had to use coins. Much to my surprise, it didn't bother me a bit.

So if the USA got rid of the dollar bill and even the $5 bill, I could probably adapt fairly quickly.

... And while we're on the topic, am I the only person who wonders why Montana is the first state to put the skull of a dead animal on its quarter?
