In Russia, where until recently US bills were the exchange medium of
choice, there was a considerable problem with the last changes of
design.
I was at firsy accused of being a forger when I tried to use a then-
new
(large portrait) bill in a remote town a few years ago.

We in Australia have been using different sizes and colours for
banknotes
of various values for some time, as in Britain.  From 1988, our notes
have
been printed on a polymer base, with a transparent section
incorporating
security features.

I assume the size differences assist blind people to get correct
change,
which must be a problem in the USA.
