Interesting comments on the Slaney siege coins, that is, "the mishap and rumours circulating in the trade that lot #359 was not quite right". The Spink Slaney Auction Catalogues detailed review of the Scarborough siege issues was very informative. Besides questioning the Type III 'Two Tower' attribution to this siege, it also raises some doubt to the authenticity of the Type I series. Given that the siege of Scarborough Castle lasted only 22 weeks, is it likely that three distinct set of main punches would be manufactured alongside different letter and number punches? The punch that was used on lot #359, is the same punch that was used on the BM example (Lockett 2574) that I believe was first published in 1819 in the Ruding supplement Part II, plate XVI, item 22, and is described as a crown siege piece, Rev. Martin Cabinet. Useful information regarding this series can be found in the BNJ 1991, "The Metrology of the English Civil War Coinage of Charles I by E. Besly & M. Cowell, and more recently in the Coin News, March 2000, "Counterfeit or Copy", by H. Manville.
