(I imagine that if people started using tons of Twos
they might keep printing them, BUT if the intent is to transition

Against them, however not totally against them. Change for 1,3,6,8,11 etc
would still need to be made. Then they could work on getting rid of the
two dollar bill like they did in Canada. Though like Canada, I think it's
best to have a one and two dollar coin.
