There is a fairly rare issue from Trier with a reverse of VIRTVS AVGG NN.
RIC VIII describes the reverse as Soldier standing holding spear and resting hand on shield.
However, I just got a nice example that clearly shows the figure on the reverse has a bare right breast, so it must actually be VIRTVS herself.
another example below it with left breast bare
