Note 1 — GREEK AND ROMAN MONEY, WEIGHTS, AND MEASURES MENTIONED BY PLINY.
John Bostock translation
In B. xii. c. 32—it is supposed by some that it is the Roman Libra that is meant, under the name of “Mina,” as containing eighty-four Denarii. If so, it must be the old Roman Libra, as it is more generally thought that the Libra of Pliny’s time contained ninety-six Denarii, of sixty grains, within a fraction.
