I don't follow his logic that I would replace dollar coins with quarters for the parking meters? That sounds like a bad idea - the cost for parking meters will go up since no one carries quarters? Sometimes I put a bunch of change in a meter, but much more often is 25 or 50 cents (and that is the only reason I have any coins - using Porter's trick of the 35mm film canister in the car, though we found it more useful to put quarters than dollars)
I thought the one commenter who said (among other things that probably aren't true) that minting new coins all the time is a waste - is there a good reason (besides collecting) to continually make new coins, rather than just print more old ones? What is the cost difference between minting old ones versus minting new ones?
How much money would we save if we stopped printing all pennies?
I think he means that for longer parking you could chuck in, say, two dollars and a quarter instead of nine quarters. People will still carry quarters, just not as many.
We could save trillions if we
1) Got the heck out of Iraq
and
2) Stopped bailing out incompetantly managed banks, car manufacturers, etc ......
