Three Guilder pieces are 11 ounces fine & when new coyned weigh out with another 1^oz. 0^dwt. 8^gr. & therefore are worth in new coyned silver money of England 1^s 8^d$\frac{3}{4}$. & a 3 Guilder piece isworth 5^s. 2^d$\frac{1}{4}$

Three Guilder pieces are by several assays are found about 11 ounces fine & when new coyned weigh one with another 1^oz 0^dwt 8^gr & therefore are worth in standard silver money of England 5^s 2^d$\frac{1}{2}$ & Ducatons are worth 3 Guilders 3 Styvers or 5^s 05^d$\frac{1}{2}$$\frac{1}{8}$. And Lewidors are there bought & sold for about 9 Guilders & 9 or 10 Styvers, or for three Ducatoons that is in our money for about 16^s 5^d, or 16. 6. The price varies constantly but has continued at about this rate in Holland for these last five or six years whereas they pass in England at 17^s, & at the rate that we value a guinea at 1^li. 1^s. 6^d they are worth 17^s. 0^d$\frac{1}{2}$.

By several assays I find that three Guilder pieces when new coyned are worth 5^s 2^d$\frac{1}{2}$ in standard silver money of England. A Guilder is 20 styvers & Lewidors are bought & sold in Holland for 9 Guilders & 9 or 10 Styvers that is in English money for 16^s. 5^d, or 16^s. 6^d. The price varies constantly but has continued at about this rate in Holland for these last 5 or 6 years. In England at the rate that a Guinea is valued at 21^s 6^d a Lewidor is worth 17^s 0^d$\frac{1}{2}$ which is about 7^d more then it is valued at in Holland.

A Ducat or five Guilder piece of Gold is in Holland valued at 5 Guilders & 6 or 6$\frac{1}{2}$ styvers that is in our money at 8^s 8^d$\frac{1}{6}$ + 6$\frac{5}{6}$ = 9^s. 2^d$\frac{3}{4}$ By its weight 2^dwt 5^gr & fineness 23$\frac{1}{2}$ carats at the rate of 4^li per ounce of standard Gold it is worth 10. 5$\frac{1}{4}$ The Holland Ducats are something coarser then the German & Hungary Ducats but pass there at the same value.
