The first zayin is possul (its a daled hafucha) according to all the seforim I checked. Can anyone find a tzad to be machshir?
See the picures above after I 1) cropped off the tagin (which were anyway not written toch kedai kesivah) and 2) after I inverted it. It's mamash a kosher daled.
This mezuzah also has many tagin not mechubar, and beisim which are round on top right - both bedieved which normally I would have fixed, had it not been for the zayin/daled hafucha.
