Cuba - Che Guevara 3 Pesos

The famous icon of revolution - CHE! His portrait appears far more often than that of Castro on many different series of coins from Cuba. I suppose this was to suppress the 'cult of personality' that purist Communists try to avoid, North Korea excepted. Of course there's a 'cult of personality' for Che! in the de-evolving West.
The type appeared first in 1990 on copper nickel, for 1992 and 1995 the coin became nickel plated steel.
