Counter marked George III Dollars 0

[BillJones]

I have been researching these coins and have not been able to find as much information as I would like. I know the first of these coins was issued in 1797 after a French invasion that the called "The Battle of Fishkill." 

Later on additional pieces were issued which had a larger counterstamp.

The Bank of England also had the Soho Mint overstrike Spanish dollars completely which resulted in the 1804 British dollars which were valued at 5 shillings.

Does anyone know how long the counterstamped coins were issued? I've read that they were issued after 1804, but I don't know if that is correct. 

Thanks for any help you can give me about this history.

Bill,

I recall Boulton made about 1 million into 1805 but with the 1804 overstrike....but my memory might not be accurate. Have you checked the references in John Kleeberg's "The International Circulation of Spanish-American Coinage and the Financing of the Napoleonic Wars." or E. M. Kelly: Spanish Dollars and Silver Tokens. An Account of the Issues of the Bank of England 1797-1816? (Kelly uses mostly secondary sources, however.) Did Doty have additional information in his book Soho Mint and the Industrialization of Money?

The Bank of England Archives are open for research and that is likely the best source.
