# Letter concerning the values of English, French and Dutch monies

In the course of Exchange, nine pounds sterling are recconed at a par with 100 Gilders specie money of Holland, or 1^{li} with 11 Gilders 2$\frac{2}{9}$ styvers. But 1^{li} sterling lately passed in Holland only for 10 Gilders & 9 or 10 Styvers, or at a medium for 10 Gilders 9$\frac{1}{2}$ styvers. The defect is 12$\frac{13}{18}$ Styvers, whereof Her Majesty allowed to the forces in Flanders 5$\frac{1}{2}$ 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 5^{s} 1^{d} sterling. And at this rate 20^{s} sterling are worth 19 livres 13$\frac{27}{61}$ sous. But 20^{s} sterling pass at Dunkirk for only 17 livres. The defect or loss is 2 livres 13$\frac{27}{61}$ sous, to be divided between her Majesty & the forces. And as 12$\frac{13}{18}$ styvers to 5$\frac{1}{2}$, so are 2 livres 13$\frac{27}{61}$ sous to 1 livre 3 sous, her Majestys proportional part of the defect: which added to 17 livres the current value of 20^{s} 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 9^{li} sterling are recconed at a par with 100 Gilders as above, the specie money of Holland is over-valued by about 3$\frac{1}{4}$ per cent. For the three Gilder piece unworn is worth only 62$\frac{3}{4}$ pence sterling by the weight & assay. And thence 9^{li} sterling are intrinsecally worth about 103$\frac{1}{4}$ Gilders. & 1^{li} sterling, which lately passed at about 10 Gilders 9$\frac{1}{2}$ stivers, is worth 11 Gilders 9$\frac{4}{9}$ stivers, & the loss by the exchange is about a Gilder whereof her Majesty bare only 5$\frac{1}{2}$ 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.
