''ov Max I'' in the reference: AYC #1 ov Max I, means that this coin is overstruck on a coin of Maximinus I Thrax. The legends of the dies having overstruck in the name of Dryantilla are those noted. As I have noted each time for all the coinage in name of Dryantilla, it is always the same obverse die. The reverse die also appears to be the same as that used for AYC #1, RIC 1 and AYC #1 ov Alex Sev, RIC 1. Therefore the obverse legend is undoubtedly the one noted and the reverse legend is 99 % certainly the one noted. 

This coin as mentioned by Numismatik Lanz München, is overstruck on a denarius of Maximinus I Thrax with the reverse SALVS AVGVSTI, RIC 4B n° 21. We see the portraiture of Maximinus I Thrax under Aequitas on the reverse with the ribbons showing that it is a denarius. The legend IMP MAXIMINVS .. can also be read on the reverse. On the obverse, one reads SALV as well as part of the original type on the left of the portraiture of Dryantilla. This same type has been overstruck with reverse IVNONI REGINE, see AYC #4 ov Max I, RIC 1. Here is what the original coin looks like:
