Thanks for the comment John but from what I can see it looks just like it but larger and higher value.
The script at the top is closer to the Crockfords one in style than the one below. as is the placement of the value.
Other side although not the side shown.

This is the one they thought it was (it isn't).

Thanks for the comment though and hope it brought back good memories of when you saw the film.
This is the type shown in Dr No though.
