Note 203 — Chapter XXX
Reading edition
The coinage of Duke Federigo consisted of Bolognini and Piccioli. The former were small thin silver pieces, weighing 19½ grains, of which 3½ were copper alloy, and forty of them made a florin. The florin, a nominal coin, thus contained 63434/59 grains of pure silver, and 146½ grains of copper; and supposing pure silver worth, as now, 5s. 6d. an ounce, it would be worth 7s. 3¼d. sterling, making a bolognini 71/3 farthings. The piccioli (33/5 to a farthing) were about the size of bolognini (52 or 56 to the ounce); but were of copper alloyed with about three per cent. of silver. All this Duke's coinage seems to have been minted at Gubbio, and it is described at great length by Reposati, in his Zecca di Gubbio. See p. 41 above, and Author's Preface.
