According to Album, the dirham of Wasit dated 126 with 7 annulets in the margin is attributed to Ibrahim.
Dirhams of Wasit 126 with 4 annulets are assigned to Yazid III.
Dirhams of Wasit 126 with 5 annulets and all 126 issues of other mints are attributed to al-Walid II.
There may be something with the annulets at Wasit but generally speaking, it's arbitrary.
