Notes on the value of French pistoles
Pistoles one with another weigh 4dwt 7grains as I find by weighing them Whence if they were standard a Pistole would be worth 17,s1d in oer money of due weight & allay. But they But they are about of a grain worse then standard & this abates of their value so as to make a Pistole worth 17s 1d money of due weight & allay.
Double Pistoles being less worn then single ones are one with another about 1 grain heavier then two singl ones & so may be valued at 34s 3d a piece But the number of these is inconsiderable.
Tere are some single Pistoles 3 or 4 grains lighter then the rest, or above. These I considered not in the recconing above mentioned. If they be included they will bring down the value of Pistoles to less then 17s 0d a Pistole. Is. Newton
If in the dead months of exportation merchants have simetimes coyned their bullion 'twas surely not to export the money afterwards but with the money to buy new bulliō for exportation.
