Memorandum concerning the values of English, French and Dutch monies

<180r>

In the course of Exchange, nine pounds sterling are recconed at a par with 100 Gilders specie money of Holland, or 1li with 11 Gilders 2$\frac{\mathrm{2}}{\mathrm{9}}$ styvers. But 1li sterling lately passed in Holland only for 10 Gilders & 9 or 10 Styvers, or at a medium for 10 Gilders 9$\frac{\mathrm{1}}{\mathrm{2}}$ styvers. The defect is 12$\frac{\mathrm{13}}{\mathrm{18}}$ Styvers, whereof Her Majesty allowed to the forces in Flanders 5$\frac{\mathrm{1}}{\mathrm{2}}$ Styvers, which is almost one half of the defect or loss by the exchange.

The par between English & French money of the new species is not yet setled by the course of exchange: but by weight & assay I find that an unworn French crown piece of the new species which passes at Dunkirk & in France for five livres is worth 5s 1d sterling. And at this rate 20s sterling are worth 19 livres 13$\frac{\mathrm{27}}{\mathrm{61}}$ sous. But 20s sterling pass at Dunkirk for only 17 livres. The defect or loss is 2 livres 13$\frac{\mathrm{27}}{\mathrm{61}}$ sous, to be divided between her Majesty & the forces. And as 12$\frac{\mathrm{13}}{\mathrm{18}}$ styvers to 5$\frac{\mathrm{1}}{\mathrm{2}}$, so are 2 livres 13$\frac{\mathrm{27}}{\mathrm{61}}$ sous to 1 livre 3 sous, her Majestys proportional part of the defect: which added to 17 livres the current value of 20s sterling at Dunkirk, makes her Majestys allowance for the pound sterling 18 livres 3 sous recconing a French crown new species at 5 livres. But her Majesty may alter the proportion at pleasure & make the allowance in a rounder number.

When 9li sterling are recconed at a par with 100 Gilders as above, the specie money of Holland is over-valued by about 3$\frac{\mathrm{1}}{\mathrm{4}}$ per cent. For the three Gilder piece unworn is worth only 62$\frac{\mathrm{3}}{\mathrm{4}}$ pence sterling by the weight & assay. And thence 9li sterling are intrinsecally worth about 103$\frac{\mathrm{1}}{\mathrm{4}}$ Gilders. & 1li sterling, which lately passed at about 10 Gilders 9$\frac{\mathrm{1}}{\mathrm{2}}$ stivers, is worth 11 Gilders 9$\frac{\mathrm{4}}{\mathrm{9}}$ stivers, & the loss by the exchange is about a Gilder whereof her Majesty bare only 5$\frac{\mathrm{1}}{\mathrm{2}}$ stivers, which is about a quarter of the whole loss. And according to this proportion her Majesty should beare but a quarter of the loss by the exchange at Dunkirk. But the rules of the Exchange where they are setled being generally followed, I presume it might be her Majestys intention to beare about one half of the loss by the Exchange in Holland, as in the recconing first set down in this paper.
