commonly called the Attic or Euboic standard. It is evident that the changes in the silver standards were due to changes in the relation of silver to gold, the fall in standard from 168 grs. to 135 grs. indicating perhaps that silver, which at first was to gold as 1 : 13, had gradually grown dearer.
Commercial Weight System.
We must now turn to the commercial weight system. As elsewhere, one of the chief commodities to come under such a system was copper, and the history of the weighing of this metal, as far as it can be learned, will be of great importance to us. Now we should naturally expect that at Athens, which had in later days but one standard for gold and silver, copper likewise would have been estimated on this unit. But, as a matter of fact, there were two distinct standards in use at Athens, as is proved by two weights preserved in the British Museum, the inscription on one of which is Mina of the Market ([Greek: MNA AGOR]), that on the other is Mina of the State ([Greek: MNA DÊMO]). This mina of the market is the same as that called the Commercial Mina on an Attic inscription[1], where its weight is given as that of 138 silver drachms, that is, the weight of an Aeginetic mina of silver. Athens had not coined any money of her own up to Solon's time, but seems to have employed the coins of Aegina. But this standard, although no longer employed for silver, did not fall into desuetude. As already pointed out, all peoples have felt the need of a heavier standard for cheap articles than that which serves for gold. Probably the Aeginetic mina had been used at Athens for copper: accordingly, when Solon made his new silver standard for the weighing of silver, the Aeginetic standard was found convenient for less costly and more bulky wares, and was therefore retained in use as the mercantile or market standard, the name State being given to the silver standard.
We have learned already that in the early stages of society copper and iron are not sold or appraised by weight, but rather by measurement. We have also seen that there is every reason to believe that the Greek obol originally was a spike or rod.]
