These are the bust descriptions from RIC VII. This is the page of plain busts. A bust can be either facing left or facing right.The term 'plain bust' means that the image is depicted with a bust only. It will not be carrying or holding anything like a shield or spear. A plain bust can be draped, cuirassed or both. The busts are bare-headed, laureate, radiate, helmeted,diademed or veiled. The diadems can be plain, rosette or pearl. There may also be some variation between the coins pictured and other coins.
    Nota Bene--Sometimes the RIC description is not correct! Exempli Gratia-- the K4 description left out rest of the sentence after the word "globe."  The I1 description is draped, but I have only seen this type as cuirassed. A few of the examples I have illustrated do not exactly match the RIC description, but were the closest I could find-- one example, the H5 type I illustrated does not have a spear.
