IVNONEM is accusative; it's unclear why it is used here but probably indicates the "motion towards" aspect of the accusative case: "toward Juno." In all of Roman numismatics, IVNONEM appears only on coins of Julia Domna, even though Juno appears on many coins over a period of centuries. It was used for three different denominations, all issued under Caracalla. Post your coins with accusative-case legends, Juno coins, Julia Domna bronzes, or anything you feel is relevant!

This is the example from the British Museum collection.

This is indeed a bit weird – accusativus directionis in the sense of "ad Iunonem" is the only sensible explanation I can think of. I have a couple of Junos. One of them is in the dative case and can be read as "for the sake / in honor of Queen Juno" (dativus finalis) or "of Queen Juno" (dativus possessivus). I tend towards the first reading.
