Notes on the value of French pistoles
The value of French pistoles stated
Pistoles one with another weigh 11.dwt 7 grains as I find by weighing them whereby if they were standard, a pistole would be worth 17s: 1d in our money. but they have been found by former Assays of old pistoles of a grain worse than standard; & the new coynd pistoles upon Assaying prove of a grain worse by which last Assays pistoles are worth but 17s.
Double pistoles being less worn than single ones, are one with another, about one grain heavier than two single ones; & so may be valued at 34:s 1d a piece. but the number of them is inconsiderable
There are some pistoles three or four grains lighter than the rest, or more. which are not worth more than s16: 11d. each
