Researching Information On The Bank Of Upper Canada Tokens 1850-1857

As some of you may know, I am currently working on a second book since 2011 about the Bank of Upper Canada 1850-1857 colonial token series (St-George and the dragon / Breton #719 & #720).

As this book deals with several topics related to these tokens, I am looking for a lot of information. Here are some examples:
Major Mint errors (Planchet Flaw, Clip, Non-standard dimensions, Off Center, Full Brockage, Second Strike, etc.);
CounterStamp/CounterMark present on this series of tokens (Excluding those that were in the Richard Cooper and Joseph Foster collection as well as those that have been sold on ebay or other online auctions in the last 5 years);
Proof/Specimen tokens (Excluding those from Bank of Upper Canada and Victoria Museum + Doug Robins, Temple and Ford's collection);
Examples of sale of a single token that exceeded a selling price of 1,500$ CAD before 2012;
Pattern;
Tokens certified by CCCS and not offered for sale within the last 5 years;
Any other relevant information.

Also, I am looking for two articles on this subject:
«The 1850 George & Dragon, A Numismate Mystery» by Wayne Jacobs (Numismatica Canada - Vol. 2 - No. 1 / March 2003);
«Bank of Upper Canada One Penny 1852 Wide 2 Varieties» by M. H. Kyle (Numismatica Canada - Vol. 2 - No. 4 / December 2003).


Please note that for most of the above elements, I am looking for at least photos so that I can be able to confirm by myself. I already have a lot of information. In particular, I am looking for information on tokens that have not been offered for sale for several years. And I'm already aware of almost everything that's currently on ebay and via other online auctions.

You can either post your examples directly on the forum, or contact me privately if necessary.

Sorry if I make syntax errors with my English...

Thank you
