|Remarks="for undertype: Svoronos 871; SNG Copenhagen 442; Köln 65. 7.19g, 23mm, 3h. The undertype obverse, featuring a portrait of Ptolemy I facing right, is almost entirely obliterated beneath the head of Zeus-Ammon from the overtype: both are aligned on the same axis. More obvious is the personification of Libya of the reverse undertype (this time on an axis 90° anticlockwise of the overtype) and the legend BAΣIΛEΩΣ ΠTOΛEMAIOY around it"
