'what your MS [presumably Thoresby’s manuscript copy of Spanheim’s book] speaks of Galba’s coin is but little, yet it has, I doubt, made mine counterfeit, but for further satisfaction I have sent a rude draught of it, and as you shall declare your opinion either for or against it so I shall regulate my own, and shall either have a mighty value for it or look upon it as common bullion. The name ‘Ser. Galba’ is against me, according to your Spanheim, and yet the face (tho’ I have not hit it exactly) is so like the face of that Emperour wherever I have seen it that I can scarce fancy that he that made the face so well could be so great a blockhead as to mistake the name; but yet allowing this to be possible, cui bono? Where lyes the plot or design that any one could have in imitateing a Roman coin? To counterfeit the metall might have turn’d to some account, but that he throws away shill worth of good gold only to try his talent of imitateing seems to me to either have the Philosopher’s stone, and that his gold cost him nought, or to have a worm in his head of no small dimensions.' (Thoresby 1912, pp. 52-3; Burnett 2020b, p. 731 n. 243)
