Thus foot, digit, palm, cubit, stadium, mile, talent, mina, **stater**, drachm, obol, pound, ounce, grain, metretes, medimrius, modius, hin and many others mean nothing exact unless qualified by the name of their country or city.

The relation is 258: 229 :: 9:8; but the exact form in which the descent took place is not settled: 1/60 or 129 of gold is worth 57 of silver or a drachm, 1/4 of 230 (or by trade weights 127 and 226); otherwise, deriving it from the silver weight of 86 already formed, the drachm is 1/3 of the **stater**, 172, or double of the Persian danak of 28.7, and the sacred unit of Didyma in Ionia was this half-drachm, 27; or thirdly, what is indicated by the Lydian coinage (17), 86 of gold was equal to 1150 of silver, 5 shekels or 1/10th mina.

At Athens the old mina was fixed by Solon at 150 of his drachmae (18) or 9800 grains, according to the earliest drachmae, showing a **stater** of 196; and this continued to be the trade mina in Athens, at least until 160 B.C., but in a reduced form, in which it equalled only 138 Attic drachmae, or 9200.

The Greek mina weights show (44), on an average of 37,9650 (= **stater** of 193), varying from 186 to.

The greater part of those weights which bear names indicate a mina of double the usual reckoning, so that there was a light and a heavy system, a mina of the drachma and a mina of the **stater**, as in the Phoenician and Assyrian weights.

The coins of the Greek dynasts and autonomous towns are struck on a variable standard with a **stater** of 170 to 180 grs.
