Maife has ceas'd to be a common Money fince the Difco- very of America by the Europeans.
Almonds are chiefly ufed where the Cauris are not current. As the Year proves more or lefs favourable to this Fruit, the Value of the Money is higher or lower : In a common Year 40 Almonds are fet againft a Pefcha, or Halfpenny Sterling ; which brings each Almond to f^ of a Farthing.

».-n° INING ' is either performed by the Hammer or the Mill. *
_ Thefirft Method is now little ufed in Europe, efpecijlly in England, France, &b. tho the only one known till the y.eari55 3 , when a new Machine, or coining Mill, having been invented by an Engraver, one Antoine Srucbcr, was torlt try d in the French King's Palace at Paris, for the coin- S?n C ° Unters - Tho fomc attribute the Invention of the Mill to Varin, a famous Engraver, who, in reality, was no more than an Improver of it ; and oihcrs to Auhry Olivier, who had only the Infpeftion of it.
The Mill has met with various Fate fince its firft Inven- l by, and the Hammer re- t footing, by the Nearnefs ■ Species ftruck with it, that there ap- pears no probability of its being again difus'd. See Mill.
in either kind of coining, the pieces of Metal are fiamo'd, or ftruck with a kind of Molds, or Coins, wherein are engra. ven the Prince s Effigies, with the Arms, Legend, £&'. the manner of preparing and cutting of which, fee under Gra- ving.
The firft Operations in coining are the mixing, and melting of the Metal.
For the ift, it is to be obferv'd, that there are no Snecies com d of pure Gold or Silver, but always a quantity of Alloy of Copper is mix'd with them : The Reafons are par* the Scarcity of thofe two Metals, partly the Neceffity of making them harder by fome foreign Admixture ■ and partly to de- fray the Expcnces of coining. See Alloy.
Now there are two Kinds of alloying, or mixing : the firft where the Gold or Silver has not been ufed for Money

Kcafon to believe, the Drachma was fomewhat the weightier. See Drachma.
The Grecian Gold Coin was the Stater Au- reus, weighing two Attick Drachms, or half of the Stater Argenreus ; and exchanging ufually for 2 5 Attic Drachms of Silver ; in our Money . . .
According to our Proportion of Gold to Silver
There were likewife rhe Stater Cyzicenus, ex- changing for 28 Attick Drachms, or

Note, Of thefe the Denarius, Victoriatus, Seftertius, and fometimes the As, were of Silver, the reft of Srafs.
There were fometimes alfo coin'd of Srafs the Triens, Sextans, Uncia, Sextula, and Dupondius.
The Reman Gold Coin was the Aureus, which weigh'd generally double the Denarius; the. Value of which, according to the firft Pro- portion of Coinage mention'd by Pliny, was

, The proportioning of the Alloy with the fine Metal is ea- iy in the firft Cafe, in the other more difficult : The Arith- meticians make a long Doflrine of it, which fee under Al- ligation.
Xet is it readily eftecfed by the following Method, taken from the anonymous Author of the Treatife at the End of that of Mr. Soifard, viz.
Write down the feveral Matters to be melted, their Qua- lity, Weight, and Finenefs, in two diftinct. Articles ■ the one containing thofe above the Standard, the other thofe under it: By calculating tho firft, you iTiall have the Excefs by the latter the Dcfefl. Then comparing the two Product, you will find by Subtraction, how much Alloy mutt be added to bring the feveral Matters to the Finenefs requir'd
For the melting, if the Metal be Gold, 'tis done in Earthen Crucibles; if Silver o. ■Copper, in Iron ones. See Crucible.
There are two Kinds of Furnaces proper for the melting of Metals 5 thofe with Wind, and thofe with Bellows : Se? each explain d under the Article Forn ice
When the Gold or Silver are in Salneo, I e. are entirely melted, they are flirr'd and brew'd together; the Silver and Copper with an Iron Stirrer, the Gold with one of bak'd Earth. In this State they are pour'd into Molds, or Frames for the catting cm into Plates, or Sheets : the Method of doing which, is exaflly the fame with that us'd by the Founders ,n Sand ; both with regard to the Frames, the

- , In each Mold are placed eight of thefe to make Plates for
Guineas, ten for Half Guineas, five for Crowns, i$c. and in proportion for Copper. All the difference between catting the Plates of Gold, and thofe of other Metals confiftino in this; that the latter are taken out of the Crucibles with La- dles and pour d into the Aperture of the Mold ; and that tor (jold, the Crucible is taken off the Fire with a kind of
