Draft of MINT00314 (Mint 19/2/172)
In the course of Exchange, nine pounds sterling are recconed at a part with 100 Gilders specie money of Holland, or 1£ with 11. Gild. 2 stiv. But 1£ sterling lately passed in Holland only for 10 Gild. & 9 or 10 stivers, or at a medium for 10 Gild. 9 stiv. The defect is 12 stivers, whereof her Majesty allowed to the forces in Flanders 5 styvers.
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 sous. But 20s sterling pass at Dunkirk for only 17 livres. The defect is 2 livres 13 sous. And as 12 stivers to 5 stivers, so are 2 livres 13 sous to 23 sous her Majesties proportional part of the defect.
By this recconing therefore her Majesties allowance to the forces at Dunkirk for 20s sterling should be 18 livres 3 sous recconing a French crown new species at five livres. But Her Majesty may alter the proportion at pleasure, & make the allowance in a rounder number.
When nine pounds sterling are recconed at a par with 100 Gilders as above, the specie money of Holland is overvalued by about 3 per cent. For the three-Gilder pieces unworn are worth only 62 pence sterling by the weight & assay. And thence nine pounds sterling are intrinsically worth about 103 Gilders. And if a recconing was grounded upon this intrinsic value of the Dutch money, her Majesties allowance over & above 17 livres would be only 15 sous. But the rules of exchange where they are setled being generally followed, & being the rules (as I conceive) by which her Majesty made the late allowance to her forces in Flanders, I have followed them in the recconing above set down for Dunkirk. Is. Newton
