As I am now adding banknotes to my collection my first Journal entry over here at PMG detailed a 1915 Mexican 'dos caritas' 10 pesos from Chihuahua .
During a recent clear-out I came across some things from ~40 years ago which was when the interest in all things numismatic started. Among the British colonial coins (all common and low grade ) I was surprised to find I had kept a reproduction of a Mexican Revolution 10 pesos banknote from Chihuahua.
I guess that means I have been interested in the period for longer than I thought. A bit scary how things work out but I suppose that means I am on the right track and now I just need an example of the real thing!
