There is another mint in Birmingham worked by a private company (" The Mint, Birmingham, Limited "), where coinages for foreign governments are executed and in addition silver and bronze colonial coins are occasionally manufactured under the supervision of the London Mint.
It corresponds to the seigniorage levied by the king on all coinages down to the reign of Charles II.
A full account of the work of the Mint, with valuable tables giving the amount of the coinage of gold and silver and bronze in the United Kingdom and the colonies in detail, and a résumé of the coinages of foreign countries, will be found in the Annual Reports of the Deputy Master and Comptroller of the Mint, which have been published since 1870.
At Corinth the unit was evidently the Assyrian and not the Attic, being 129.6 at the earliest (17) (though modified to double Attic, or 133, later) and being divided by 3, and not into 2 drachms. And this agrees with the mina being repeatedly found at Corcyra, and with the same standard passing to the Italian coinage (17) similar in weight, and in division into 1/3 -- the heaviest coinages (17) down to 400 B.C. (Terina, Velia, Sybaris, Posidonia, Metapontum, Tarentum, &c.) being none over 126, while later on many were adjusted to the Attic, and rose to 134.
