-->Vll.6.v. Let none dare to refuse a gold solidus of full weight, to whomsoever it belong, if it be not debased; nor require money of less weight for anything of his. Whoever shall do anything against this rule and refuse a gold solidus of full weight that is not false, or seek reward for changing it, shall be arrested by the judge, and compelled to pay three gold solidi to him whose money he refused. And one third of a solidus shall be kept by the judge.

Xll.3.xviii. One pound of gold is worth seventy-two solidi of gold. One uncia is worth six solidi. A stater of gold is worth three solidi. A drachma is worth twelve silver solid. A third of a gold solidus is worth five silver solidi. A seliqua is worth one and a third silver solidi.
