Honestly nickels and dimes, and maybe even quarters, should go too. It's ridiculous that we don't have $1 and $2 coins in widespread circulation in the US (we have a $1 coin but nobody uses it).
replies(8):
I never understood the objections to the $1 coin, especially after the redesign to make it more distinct from a quarter. $1 coins are great for buying stuff out of vending machines since you don't have to fight with a dodgy bill acceptor or a mangled bill.
1) Bring back the $2 bill (it had not been printed for a decade+)
2) Redesign the $1 coin (Eisenhowers being too big and heavy)
3) Stop printing $1 bills
Unfortunately they never got to step 3, which made 1 and 2 pointless, and here we are.
