In a vain attempt at sorting out auction catalogues at home I found a small book buried in their midst.
This was 'Coins & Tokens of Tasminia 1803 - 1910' by Roger V. Neice. As a collector of British Colonial issues and those of the Napoleonic period it was refreshing to go through this again as it includes all the various types of 'money' that circulated in Tasminia with plenty of historical context conveying the variable fortunes of the island and its people. To say Napoleon's influence was global would be an understatement as Tasmania is about as far away as you can get!
It also prompted a quick search of the auction archives for some of the rarer issues - it appears that proof examples of some of the early tokens now command serious money .
This interesting find has renewed my hope of finding my other 'missing' books and I know that I have some actual Australian and New Zealand tokens somewhere although I expect it will only be 'moving house' that finally explains all the disappearances.
