5.44d. The Cologne Mark, according to
Pegolotti, was the same, and the Venice Mark of silver was = 1 English
Tower Mark + 3-1/2 sterlings (i.e. pence of the period), =
therefore to 2l. 4s. 4.84d. The French Mark of
Silver, according to Dupre de St. Maur, was about 3 Livres, presumably
Tournois, and therefore 2l. 2s. 11-1/2d.
[4] Cibrario, Pol. Ec. del Med. Evo. III. 228. The GOLD FLORIN of
Florence was worth a fraction more = 9s. 4.85d.
Sign. Desimoni, of Genoa, obligingly points out that the changed
relation of Gold ducat and silver grosso was due to a general
rise in price of gold between 1284 and 1302, shown by notices of other
Italian mints which raise the equation of the gold florin in the same
ratio, viz. from 9 sols tournois to 12.
[5] For 1/18 of the florin will be 6.23d., and deducting 1/6, as
pointed out above, we have 4.99d. as the value of the
grosso.
I have a note that the grosso contained 42-88/144 Venice grains of
pure silver. If the Venice grain be the same as the old Milan grain
(.051 grammes) this will give exactly the same value of 5d.
