UNLISTED ISSUE. According to the preliminary study published by Genio popvli romani, not only T|F/PTR emission was continued after the 1/96 reduction [RIC VII TRIER 39-60] but also the emission of unmarked folles with bust of Mars on reverse [RIC VI TREVERI 877-885]. The main problem is to distinguish this later part from the earlier one, issued on the 1/72 standard. As Sutherland wrote in RIC VI (footnote 1 on p. 227): "It is not always easy to distinguish this earlier and heavier unmarked series from the lighter one, with the same types, which appeared after Maximinus' death: the weight-peaks are quite distinct from each other, but the light 'heavies' and the heavy 'lights' inevitably tend to overlap".

Probably the most crucial data is not a weight, but a diameter of die (PRD), i.e. pearl ring diameter (which should be not confused with a diameter of flan!). For earlier and heavier coins, issued on the 1/72 standard, we may assume that the diameter of beaded circle is at least 21 mm. For lighter coins, issued on the new 1/96 standard, this diameter is significantly smaller - c. 19 mm.

Of course, it is sometimes hard to extrapolate a diameter of die from a diameter of actual flan, so the attribution is not always certain.

Note that the 1/96 emission was continued up to 316, which is proven by the die match discovered by Genio popvli romani. Compare obverses of coin from 1/96 emission with Sol [2.99 g; 19-20 mm] and of coin from T|F/ATR emission [2.90 g; 19 mm; TRIER 113].

Coin should be listed after TRIER 60.
