'As to your own Duplicats of Saxon and Roman ancient Coyn in all Mettals, I’me most willing to let you have ancient Scotch pieces in exchange for such of them as I want, but it would be a very tedious bussienesse to draw out for you a Catalogue of all my Desiderata, there being many hundred Coyns of one and the same Emperour, differing in Reverses or Inscriptions on both sides, and I being desireous of all the varietes I can possibly purchasse. I would think it therefore much easier for you to send a List of your Saxon and Roman Duplicats, their Mettals, sizes, Stamps, with Inscriptions on both sides, that I might give you notice of them I want, and if ye have already any ancient Scotch Coyns ye may also let me know what they are, that I may supplie you with such as ye want. After I have heard from you I shall send my Duplicats to a friend at London who will be ready to deliver them to you or your Order, and receive what ye send to me. ... I bought lately in a Goldsmiths Shop a large Nero of Gold truly antique weighing upwards of ane unce, but could not be informed whether It have been found in this Kingdome.'
