Thank you for those valuable information on the variety and 
recurrence of scrips.

One important detail on Fisher's proposal of 1932-34 and a related 
series of scrips during that period was that there were stamped 
scrips, ie there was a scheme intended to enforce their circulation 
by making the scrips decline in value with time. Keynes had a talk on 
such an idea, when presenting Gesell's ideas in his General Theory.
