The distribution curves constructed from the summarized mass distribution of the four mling families (Gordian III, Philip, Decius and Gall) can be seen in Fig. 5. The numbers of coins (frequency) can be seen from the height of the bell-shaped curves. The largest number of coins are from the fantilies of Gordian III and Philip. The decline of mass was a very slow process during the 11 yearsof the reign of Gordian III and Phlip I as can be seen from the coordinates of maximum. The decline of coins became more significant with Decius' reign. The decline of coins was larger during his two years' reign than it was during Philip's five years' reign. After this time the decrease of mass of coins became fast. The decline of coins was larger during Gall's and Volusian's reign than it was during the previous thirteen years. The average decrease of the mass of coins was 0.2—025 g yearly. This is 6—8% loss of value without calculating the decrease of silver content of coins.
