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

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

By several assays I find that three Guilder pieces when new coyned are worth 5s 2d$\frac{\mathrm{1}}{\mathrm{2}}$ 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 16s. 5d, or 16s. 6d. 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 21s 6d a Lewidor is worth 17s 0d$\frac{\mathrm{1}}{\mathrm{2}}$ which is about 7d 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$\frac{\mathrm{1}}{\mathrm{2}}$ styvers that is in our money at 8s 8d$\frac{\mathrm{1}}{\mathrm{6}}$ + 6$\frac{\mathrm{5}}{\mathrm{6}}$ = 9s. 2d$\frac{\mathrm{3}}{\mathrm{4}}$ By its weight 2dwt 5gr & fineness 23$\frac{\mathrm{1}}{\mathrm{2}}$ carats at the rate of 4li per ounce of standard Gold it is worth 10. 5$\frac{\mathrm{1}}{\mathrm{4}}$ The Holland Ducats are something coarser then the German & Hungary Ducats but pass there at the same value.
