Analysis - ÓVÁRI Ferenc: On the metrology of antoniniani originating in the 3rd century

IMP. CAES ... are from earlier issues. Regarding the antoniniani of Philip I, the coins with the obverse legend IMP. M. IVL. PHILIPPUS A VG were issued earlier than the coins with the legend IMP. PHILIPPUS AVG. The metrological data of the two groups of coins are summarized in Tables 1-4. and the differences can be considered from these data.

It is clear from the data of Tables 1-4 that the rules are the same in all the four groups [1]. The average mass of coins decreases monotonically. The exception is in the case of Aemüian's mint, where the limited number of these coins [4] distorts the evaluation [2]. The average mass of coins from Antioch is much larger than the mass of those struck by the Romans. The difference can sometimes be more than 15%. [3]. The coins of emperors' sons are lighter than the coins struck for their fathers name. The average mass difference between Decius's coins and his son's coins is exceptionally large [4]. The masses of the coins of Singidunum and of Smyrna are the same in all the four tables; however, the average mass of Tulln's hoard is smaller than the others in almost every case. The difference is 0.1 - 0.2 g or more and it is significant. The origin of the quite large mass difference cannot be discovered un-
