Sure, I deliberately simplified the story in order to get across the point that it is when a currency supply is controlled and has a good supply is multiplies to its ability to trade.
Also how the value of a currency can be based upon the stability of an empire.
Just as is the dollar today is backed only by the US itself.
Of course when a Govt over creates the supply then inflation comes into play.
But this was another point I did not want to bring in at this time and one I intended to bring up in another blog. I try to stick to one or two points as I find people then take it in
There are many theories on Roman history and I have heard and read as many as there are books on the subject, but it does not alter the fact that during this time of the copper coins of Rome´s economy that it boomed, and when the this money supply as taken out of circulation it created a depression.
I have discussed this in depth with the american historian Bill Still of whom I am a big fan.
Thanks for the comment.
