That different values of coyns create confusion & tricking in Trade

That tis best that the coyns should pass at one & thesamme value in all the Plantations to prevent the drawing money from one Plantation to another

That a Table of the just value of the coyns be annexed that upon stating the value of any one species, the value of all the rest may be known.
