Hardly. Formerly great Britain once had coinage in denominations as small as a quarter of a farthing, which had a value of one-sixteenth of a penny.
I still have a ha'penny (one-half of a penny) I was given in change when I visited there long enough ago that the 1/2-p was still in circulation.
Until they discover a way to prevent inflation (without strangling the economy), over a long enough period of time, it is inevitable that currency will be reduced to an insignificant value and be "demonitized."
