I think it´s neither a imitation nor a coin. It´s stamped only on one side, decentered, non-circular in flan and stamp, might be a private, maybe religious token. What about a Annunciation scene?

Imitation doesn't necessarily mean it has to be accurate, certainly not meant to deceive (it's not a forgery) and not necessarily used as a coin (monetary function) by those who made it. It may have been used as
obolus in graves, for instance. A similar case that
comes to mind are imitations of seventh-century
Byzantine solidi, stamped on one
side by tribes from the Caucasus. With no archaeological context for the coin in question, we can only speculate.
