Well here I am over at the PMG Journals with my first banknote - a 'dos caritas' 10 pesos from the Mexico Revolution 1910-1920. As my main collection evolved into Napoleonic coins you may ask 'where the *>?^ did that come from?'
As Napoleon conquered most of Europe my collection of French coins started to also encompass those issued in Italy, Westphalia, Holland and Spain as family members took charge of these territories. The impact of the ever changing European map was felt globally, most notably initiating the collapse of the Spanish Empire, and having started by collecting British small silver I found that I was picking up a few fractional reales from this period with most of the examples being from Spain itself, and Mexico. Due to a preference for 'real money' in the early 1800's there was a lack of 'paper money' so I jumped ahead about a hundred years or so to another turbulent period in Mexico's history - the early 1900's. Not only did I find the often classical designs of the earlier notes issued by the 'Bancos' attractive this was a period I really knew nothing about, the currency was incredibly diverse and rapidly changing across the whole region, and so it was a great opportunity for discovery and to learn something new.
I realise that this is a common note and you could probably buy the whole denomination set immediately on Ebay but these would be lower grades and/or expensive - one thing collecting coins taught me is that quality (and rarity and preferably both) counts and this top grade note was not much above the grading cost. For anyone who also reads the NGC Journals you will no doubt be aware that one of my passions in coins is the search for die varieties and even for this note there seems to be at least 23 options (not including control letters etc*) with mine# probably the easiest to find in high grade, but you have to start somewhere!
*Mexican Paper Money 2017 highlights 'the dos caritas series from Chihuahua, are collected by series, control letters and numbers which total in excess of a 1,000 notes'. This is NEVER going to happen.
