The top coin is a quadrans with Hercules on the obverse and a ship's prow, right, on the reverse. The seller called the coin Cr 106/7a - Staff and Club series from Eturia. The a means the reverse has a staff, and there is no club on the obverse. I am not sure what qualifies as a staff on the reverse. If the line is not a staff, the attribution would be: Cr 56/5, Anonymous series from Rome. Crawford notes both Cr 56/5 and Cr 106/7 are known to have been struck over Cr 38/6. What do you think? The undertype is a Roma left / prow right semilibral uncia, Cr 38/6 from Rome. The back of Roma's helmet and neck and the mark of value are visible below Hercules head. On the reverse a curved back of a ship;s prow and two soldiers is visable. There are many variations of style of uncia. The best fit for what I see was from the Vecchi sale in Sept 1996, lot 30. I bought a similar overstrike a few years ago. That seller did not give Crawford numbers for the top of bottom coin dies.
