For my sins, I was almost a Classics major . . . and since I'm Catholic we do a LOT of Latin every Sunday. :-)

It reads:
[Obverse] JACOBUS (James) D.G. (Deo Gratia) MAG(na) BRI(tannia) FR(ance) ET (and) HI(bernia, i.e. Ireland) REX (King)

[Reverse] FACIAM EOS IN GENTEM UNAM (I will make of them one people) from Ezekiel 37:22.

Coin was commonly called a "Jacobus".

Magna Brittannia? Darn. I was hoping it was MAGA Brittania.
