To the RtRight Honble:Honourable the Lords Commrs:Commissioners of Her Majestys Treasury

May it Please Your Lordships

In Obedience to Your Lordships verbal Order concerning the Value of several standards for Plate we humbly lay before your Lordships

That old Plate of eleven ounces two pennyweight of fine silver in the pound weight Troy being of the same standard with the money is of the same value wch:which is 5s: 2d ꝑper ounce.

That new Plate of eleven ounces ten penny weight of fine silver in the pound weight Troy is worth 5s: 4d & 26111 parts of a penny of about 5s: 4d14 per ounce.

The Plate of Ten ounces 15 penny weight of fine silver in the pound weight Troy would be worth 5s & 5111 parts if a penny, or 5s and about the sixth part of a farthing ꝑper ounce. And if the Fraction which is inconsiderable be neglected, it may be reckoned at 5s ꝑper ounce. That Plate of ten ounces four pennyweight of fine silver in the pound weight Troy would be worth 4s. 9d. wanting about the 9th part of a farthing ꝑper ounce. And if the fraction wch:which is inconsiderable be neglected, it may be reckoned worth 4s: 9d ꝑper ounce. That Plate of eleven ounces of fine silver in the pound weight Troy would be worth 5s: 1d12 ꝑper ounce abating 13222 parts of a penny or a quarter of a Farthing. And we further take leave to make as near an Estimate as we can of the value of the Plate already made That old Plate is worth about 5s & a farthing ꝑper ounce for an abatement must be made of about 6d. or 7d. ꝑper lwt.pound weight for the worseness of the plate, & 10d. or 12d ꝑper Lwtpound weight for the worseness of the Soder, & 1d. for the Charge of melting it into Ingotts & 2d12 or 3d ꝑper lwtpound weight for the Waste in that melting, that is in all about 21d ꝑper Lwtpound weight, or seven farthings ꝑper Ounce. That new Plate according to the best of our Iudgements is worth about 5s: 2d14 ꝑper ounce, for an abatement must be made of about 8d. or 10d. ꝑper Lwtpound weight for the worseness of the Plate, & 10d. or 12d. ꝑper Lwtpound weight for the worseness of the Soder and 1d ꝑper Lwtpound weight for the charge of melting it into Ingotts, & 2d12 or 3d ꝑper Lwtpound weight for the Waste in that melting, that is, in all about 2s. ꝑper Lwtpound weightor 2d. ꝑper ounce. All wch:which is most humbly submitted to your Lordships great Wisdom C P. Is: N I. Ell 25. Apl. 1711.
