The die engraver turns his attention to the obverse design in this group. His only reverse variation of any significance is the variety illustrated, where the head of the driver's sceptre is now trefoil shaped. He is unsure of how the design in front of the face should go, and he makes a number of experiments. The only thing he is certain on is that the mouth design should no longer be the simple "V" shape that it has been up to this point. He adds some lines to connect the lips to the rest of the face. This is the last group in Class V. In the next group he changes the nose design to that which defines Class IV. Remember, the classes are subjective divisions, as are the design groups. It is only the series, and the chronological position of any die within that series that is truly objective.
