Bank Of England 1804 Counterfeit Dollars - Scientific Study

For many years I have been collecting Bank of England silver-plated dollar counterfeits. My motivation is understandable: I am a local historian and a fellow by the name of William Booth, executed in 1812 for forging BoE banknotes, engaged in his illegal activities less than a mile from where I live. He also counterfeited all denominations of BoE tokens and was without a doubt the most prolific forger of the Regency Era. Some of these coins were found on his premises in Victorian times and are now in a local museum. I have photographed these coins and have actively been buying examples which fit their profile. I now have 30 examples of Booth's dollars and have approached the materials science department of a university. They are interested in setting up a detailed scientific analysis (SEM-EDS and other techniques). It will be a ground-breaking study and should hopefully reveal much about Booth's production methods.

I would be very grateful if those of you with plated BoE dollar counterfeits could let me have good scans of your coins to add to the growing database of images I have now accumulated. I am also interested in buying more examples if you have any for sale. Thank you in advance for your assistance! I
