"Since you hold my views on the matter in such contempt, this conversation cannot be any more pleasant for you than it is for me. Let us bring it to a head directly," Isaac suggested. "You have offered a way to get me out of difficulty in the event that Bolingbroke demands a Trial of the Pyx. But this is of no utility to me if he doesn’t . For as all the world knows, he has been gathering in guineas of late, preparing to assay those coins that have been circulating in her majesty’s currency. Many counterfeits shall be encompassed in any such sample. At any time of Bolingbroke’s choosing he may change his tune, and say, ‘Behold, the Pyx was tampered with by Jack the Coiner, its contents are no reliable sample of the Mint’s produce, we must instead assay the coins in circulation.’ Such an assay shall prove deficient, both in the weight of the coins, and the fineness of the metal, because it shall include so many counterfeit guineas."
