Intro'd
by Caracalla. Made famous by the army- emperors. Commonly called
'Radiate'. |
Extra: The coin was
introduced by Caracalla wearing the radiate crown, signifying it as valued
at twice as much (though it's weight was only max. 1,6 as much). Though at
start the coin consisted of 60% silver this deteriorated steadily to
fund the (internal) wars. After the capture of Gallienus' father G. minted
more than a million a day (!). By now the coiners had stopped lessening
the silver % an heightening the mix of bronze and tin. Now the flans were
of a 5-10% silver and then pickled so that the copper on the surface of
the coin was leached away. When struck these coins generally had such a
thin silver layer that it rapidly wore away. Aurelian (270 ad) tried a
monetary reform in which the Antonianus was put at a 20 parts to 1
part alloy (thus the XXI sometimes found on a coin). Bu this did not hold (as
Aurelian didn't). The Antonianus met the end of its product life-cycle
with Diocletian (300 ad). |
