Note: On this coin, Isis seems to be holding beaded circlet, maybe a form of rattle. On other coins from the Rome mint this object is clearly a leafy wreath; in yet others it is indistinct. Coins from the Laodicea mint show no such object, just the hand at the breast (subject to correction if someone finds one that does!). I suspect that the original intent was to show Isis offering her breast (which is the description given in the British Museum catalogue), and that the hand pushing at the breast was transformed in the Rome mint into a range of ill-understood objects, in the same way that the stern of the ship was shown correctly in Laodicea but was sometimes shown as a quite separate and distinct altar in Rome.
