Two reports on foreign coin in Ireland
To the Rt Honble the Earl of Oxford & Earl Mortimer Lord H Treasurer of great Britain.
May it please yor Lordp
In obedience to yor Lordps Order of Reference signified to me by Mr Taylour in his Letter of Iune 16th Instant, I have perused the Representation from the Lords of the Privy Council of Ireland touching a late Order of Council here for giving currency in that Kingdom by Proclamation to some forreign Coynes wch were omitted in a former Proclamation, a printed copy of wch they have sent, desiring a clause to be added to the said Order for making such {allowan}ce for light pieces as was made in the said Proclamation, & that {the Order} may comprehend also the forreign coynes mentioned in that printed {Proclamatio}n because the original therof under the broad\great/ seal was destroy{ed in the} late fire wch happened there at the Council Chamber, so that {the Cler}k of the Council cannot now certify that the printed copy {agrees wi}th the original verbatim as the late Act of Parliament requires {for} the conviction of counterfeiters of those coynes. And upon comparing the said Representation with the said late Order of Council & printed Proclamation, I humbly represent that the weight of the single Pistole & Lewis d'or being in the said Proclamation put 4dwt 8gr, the weight of the double Pistole & double Lewis d'or ought in proportion to be put in a new Proclamation 8dwt 16gr & that of the quadruple Pistole or dou{illeg}|bl|e doubleon 17dwt 8gr. And that if the Moyder of Portugal (wch as the Merchants bring them hither a little worn weigh one with another 6dwt 21gr, & before wearing may be a quarter of a grain heavier or above) may be put in weight 6dwt 22gr in the same Proclamation & valued at thirty shillings. For in Ireland where an English shilling passes for thirteen pence the Moyder of this weight is worth 29s 11d reconning gold 22 carats fine at 3li 19s 8d per ounce wch is the standard value, or \it is worth/ 30s 00d reconning gold 22 carats fine at 4li per ounce as is ordinarily done: and 30s is a medium & the nearest round number. And a grain being allowed for wearing, this piece will be current till it weights but 6dwt {{illeg}|21|}gr as was stated in t{{illeg}|he|} late Order of Council. And after that it will be current still by abating 2d per grain in its value for what it wants to the weight of 6dwt 22gr. For the latter part of the printed Proclamation concerning the allowance for light pieces & concerning the scales & weights for weighing them, I am humbly of opinion should be continued in the next Proclamation.
I humbly beg leave to represent further to yor Lordp th{{illeg} {illeg}|at the|} wa|e|ights & values of the silver coynes in the printed Proclamation \would/ answer better to {illeg}|o|ne another & to the coynes themselves if two pence were taken from the value of the Crusado & \eighteen or/ twenty grains added to the weight of the Dollars. For the Crusad{e}|o| is reconned in Portugal to be the tenth part of the Moyder in value & the Moyder is worth 30s in Ireland as above, & yet the Crusado is valued in the Proclamation at 3s 2d. Its weight before wearing is 11dwt 4gr. In the Proclamation its weight is put 10dwt 20gr, & a Crusado of this weight is worth but three shillings|.| in Ireland
Rix Dollars Cross Dollars & other Dollars are in the Proclamation put of the same weight & value with pieces of eight of Mexico & Sevil, Pillar pieces & Lewises. And yet the Dollars are much coarser & heavier than the pieces of eight & Lewises & ou{illeg}|gh|t to be 18 or 20 grains heavier to be of the same value. Rix Dollars before wearing weighed about 18dwt & 6 8 or 10 grains & Cross Dollars 18dwt 1gr. That they may be worth 4s 9d (wch is their value in the Proclamation) they should weigh at least 17dwt 18gr.
I am therefore humbly of opinion that the gold coines should be of the weight & fineness expressed in the Paper hereunto annexed, & the silver ones as in the printed Proclamation, unless for the reasons above mentioned it should be thought fit to take two pence from the value of the Crusados & add eighteen grains to the weight of the Dollars.
All which is most humbly submitted to yor Lordps great
wisdome
