Afraid not and I can't see anything that specifically matches in Eaglen. (Pages 136-157 http://www.britnumsoc.org/publications/Digital%20BNJ/2001.shtml )
However the lack of prices, use of 'King' and presence of both a ticket to go with the coin and a 'stock' one suggest a collector rather than a dealer to me.
The fact that they have gone to the care of writing the roundel first in pencil then inking in supports that to my mind. I suspect most dealers just want something to remind them what it is and how much to charge, so rattle off their tickets rather more casually.
Obviously use of a fibre tip pen means they are relatively modern, but the style is traditional ...
Not much help I'm afraid.
