Your coin is
RIC VI TREVERI 862
RIC VII TRIER 53 looks like this coin:
The cloak is an important difference. But the more important difference is
weight and the most important difference is
diameter.
It is worth to remember that during this TF/PTR issue follis/nummus was significantly
reduced: from 1/72
Roman pound to 1/96 (from ~4.5 g to ~3.4 g).
RIC VI TREVERI belongs to 1/72
part and
RIC VII TRIER to 1/96
part. However, these coins were minted in al marco mode. 96 coins weighted 1 pound but one
flan may have been significantly different from another. As a result, in one batch of coins, there could be coins having 4 g and those having 3 g. But the
diameter of the DIE was nearly constant. ~22-23 mm for
RIC VI TREVERI and ~19-20 mm for
RIC VII TRIER
The
diameter of the
flan of your coin is practically the same as the
diameter of the die, i.e. pearl ring, so this 23 mm proves that this coin
comes from the earlier
part of TF/PTR issue
And I am pretty sure that this
RIC VII TRIER 53 on
Wildwinds is in fact another
RIC VI TREVERI 862.
