Hi Trev,
There is no evidence of another mark beneath the Z or the crossed Z's. The Z on the far right is in a slight depression as if it was a cartouche but I do not believe the marks are formed as such. I can see no sign of overmarking (other than a Z over a Z) or old punch marks being filled either. Weird.
