☉ Zacheen of Venice 2^{dw^t} 5^gr. / 23 carats 3^gr. 22. 23 $\frac{3}{4}$ ∷ 88. 95 ∷ 53:

{illeg} Ducat 14^{dw^t} 18^gr = 354^gr. 11 $\frac{1}{10}$ ∷ 354

In one parcel

27. Guineas & 2. $\frac{1}{2}$ Guineas Bad, & 14 Good Guineas

In another

15. Guineas & $\frac{1}{2}$ Bad. 9. Guineas & $\frac{1}{2}$ Good

In another.

83. Guineas & $\frac{1}{2}$ bad. 33. Good

A Venetian Zacheen of ☉ weighs 2^{dw^t} 5^gr is better 1^car 3^gr equals 57^gr $\frac{3}{14}$ of our standard gold.

A Venetian Ducat of ☽ weighs 14^dwt 18^gr = 354^gr is worse 1^oz 4^dwt equals 315 $\frac{3}{4}$ ^gr of our standard ☽.

In Venice a Ducat is 124 sols & 3 Ducats 12 sols (= 977 $\frac{2}{3}$ grains of our standard ☽) is the value of a Zacheen at Venice

In Holland & Germany a Ducat of ☉ is better & weights 2^{dw^t}. 5^gr.
