The three \spanish/ pieces of Spanis two Ryals of {st silver} wch I received\wch were sent to me/ by yor Lordps order |{to} be examined| are very unequally coined. One of them \weighd/ 3dwt 614 grains & is 412dwt worse then our standard. Another weighs|d| 3dwt 13grains & is standard wanting only a {qu}{illeg} scant. A third weighs 3 dwt 1023gr & is 412dwt worse. These three & that wch by your lordps order I caused to be assayed some months\weeks/ agoe & wch was in weight assay 312dwt worse then standard, & weighed {illeg} 3dwt 6gr, are one wth another at a medium \in weight/ 3dwt 9gr &\&/ in weight &\Assay/ 3316dwt worse than sta & in value 10d{?}{?}516.\+[1]/ And if a Mexico pice {sic} of eight be worth 4s 6d then 800000 pieces of eight will make [418909{4}] about 4189000 two Ryall pieces of K. Charles.

5 Carolu's & 29 of a Carolus equal a Mexico piece of 8. 47 Caroluses equal 9 pieces of 8 & 8000000 pieces of 8 should make 4180000 Carolusses.

If a piece of 8 be recconed at 54d, 800000 pieces of 8 will make 4189100 Carolusses. But 13 per {illeg}|1|00 abated brings it to 4175000

[1] And [five of these two Ryall pieces are almost 5 per cent better\worse/ then a Mexico piece of eight] a Mexico piece of eight \worth 5|4|-7|6|/ is almost 5 per cent better \in value/ then 5 of these two Ryal pieces. And if 800000 {illeg} such Mexico pieces of 8 will make 4{illeg}|18|9000 \such/ two Ryal pieces
