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.
But I've never found a retailer willing to give a $2 bill as change.
The resistance to the $2 bill is a very weird cultural thing.
Further, since I don't have enough pockets to have a dedicated change pocket, it's always getting caught up in my keys and/or pocket knife.
Nobody really gave us training on this stuff, do other countries use a coin purse or some such?
Lastly, they're just comparatively heavy.
I just carry cash around in either a clip or a "front pocket wallet" I think they're called, and it seems more convenient all around.
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.
Mostly retailers don't stock $2 bills (because they're weird), so if a customer brings a $2, the cashier will put it in their their exceptional bills area, which usually is just large bills. No change is made with exceptional bills, so twos don't get recirculated.
