'The book has an elaborate hand-written dedication by its author to Folkes on its title page:
- Martino Folkes Anglo-Britanno, R.S. Londoni V.P.
- D.D.
- Nobilissimus Josephus Niccolini \olim/Eques Hierosolymitanus. nunc Sacri Ordinis Sancti Stephani, Florentiae, postridie Calendas Novembris 1734.
The text of the book has been annotated with a series of numbers, explained by Folkes on p. 43:
- The written numbers following many of the medals express their weight, as taken by Cavalier Nicholini for his own use, in Deniers and Grains of the fflorence ounce, which I take to be the same as the Roman and equal to 438 Troy Grains.
- I have since reduced them to Troy Grains for more ready use.
- The numbers of the 1 margin of some of the pages are the weights of some gold medals I weighd of the Great Dukes.
Both sets of annotations are in the same (Folkes’s) hand so he must have copied out the weights taken by Niccolini from some other source, perhaps a series of tickets, or perhaps a notebook. As a result, Folkes had the weights of a total of 183 gold coins available to him (169 Roman imperial, and 15 Greek). To them he had added the weights of another 69 coins from the Medici collection, concentrating mainly on the coinage of the Severans and the third and early fourth centuries, together with coins not listed by Niccolini (Republican gold, and more Greek). The Medici collection was far richer, so it is clear that Folkes had weighed only the coins where he was specially interested, or where he was lacking information from the Niccolini collection.
There are also further notes by Folkes at the beginning and the end of the book. It is simplest to describe them in order. The pages at the beginning of the book contain:
- a list of ancient denominations and their ancient equivalents; the Roman and Florentine pound the same as the English; a list of Roman denominations;
- a metrological passage on the Roman pound from Lucas Paetus; quotations from Celsus and Fannius on values of ancient coins;
- notes on Roman monetary history and coins, with two references to Venetian coin history;
- quotations from Vitruvius, Vaillant, Plautus, and Suetonius; remarks on a Republican coin in Vaillant;
- a diagram of a ‘Curva Asymptot.’;
- Chronologia Romanorum Monetaria.
At the end of the book are more pages of annotations:
