I hope you are right. Can't speak for the US, but in Canada it does not seem likely. Paper bill currency is replace by coins as inflation keeps robbing the people. Canada retired the dollar bill with the loonie around 1987. Then .the 2 dollar bill went and comes the toonie in 1996. Then the penny went as it has more metal melt value. Next will be birth of the 5 dollar coin while 5 dollar bill and 5c go join the Dinos in the museum.
