Moneta est justum medium et mensura rerum commutabilium

Moneta est justum medium et mensura rerum commutabilium, nam per medium monetae fit omnium rerum conveniens, et justa aestimatio. Money is the just medium and measure of all commutable things, for, by the medium of money, a convenient and just estimation of all things is made. Dav. 18. See 1 Bouv. Inst. n. 922.
