The two coins illustrated below are examples of the same type of coin.  Although from different dies, both coins show the same configuration of the eagle on the reverse and both show the same control mark under the eagles legs.  As shown in Part 1, coin A was produced during the time of Ptolemy IV and is therefore dated within 221 to 204 BC.

While coin A is certainly dated to the time of Ptolemy IV, coin B is also certainly dated;  however, in this case, to shortly after 180 BC in the time of Ptolemy VI, at least some twenty-five years after coin A.  How can this be ?
