AE 16 mm, 3.47 g, Ake Ptolemais mint BCE 175-c. 173/2
SC 1477.2j (this coin illustrated on page 60 of SC Vol. II Part II "fig. 9" and identified as 2k).
Text in SC reads "Antiochus IV brockage demonstrating that central cavities and circular scratches were on the flan prior to striking" coin is also mentioned in the text above the photo that accompanies the description.
Control is definitely M (2j) rather then the M monogram as shown in 2k.
