The link below provides an interesting take on the history of money, this video baked my noodle the first time iviewed it. This video comes in 22 parts on you tube.
Frankly the interviewers style /presentation is painful, you feel like grabbing his pen and placing it where the sun don't shine. Neverthless a very intersting overview of how we got to where we are today.
Plow on thru the first 10- 15 minutes as the video really gets intesting once they get to the part about the establishment of the Bank of England.
Its an old video but history is a great teacher.
