JBK is right...given the choice between paper and coin, paper dollar notes won.
So the mint hears that IKE's are too big and heavy and they produce Susan B.'s which are just a hair larger than a quarter...from one extreme to the other. (Insert "Homer Simpson" Doooh here)
O.K....let's get it right and produce SAC's. I like the size, weight and color of this coin. I would like to see some of the concept designs as previously discussed, but again...given the choice between paper $1 notes and coins, the public would rather have notes. How could you have paper dollars over a dollar coin that "could" look like this?
Until the government stops making $1 notes altogether, a dollar coin will never be received which is sad for us collectors and the US tax paper that continues to spend $500 million per year producing dollar notes that last no longer than 16 to 18 months before they are destroyed.
How long does your average coin last? 50 years? Makes sense too much sense to me!
