It's artfully reproduced (no pun intended) original appearance on the coins certainly reminds me of First Millennium descriptions of the idol housed at the kaaba, IIRC today alone at a much older desert pilgrimage site that was for centuries a central location for more than two hundred similarly revered idols "of every description."
Presently, "there is no other god" than Allah, and Hajar-al-Aswad is now alone at this focus of all Muslim worship, at Mecca.
I suppose it's no stretch.
