If they end up being cheaper in the long run because they last longer than paper bills, I'd be for it. Used to get the gold-colored ones once in a while, and I didn't like them so much. Don't know why, I had nothing against Susan B. Anthony or feminism, just didn't like them. But, as I say, if we don't have to keep the printing presses running so much, it would be worth it to me.
Another saving would be if they didn't have to change the date every year, and of course, they wouldn't have to use any resources to keep track of the serial numbers, as with paper ones.
One cost to the private sector, though, would be swapping out change-making machines and coin-operated vending machines. And coin-counting machines.
