Reverse 1st Diagnostic : Pronounced vertical die crack originating from top of Britannia's head, undulating/squiggling at 2mm distance from the inner rim border, terminating precisely at the baseline of the first N.
Reverse 2nd Diagnostic : Associated branch crack extending leftward into the olive branch cluster, manifesting as a faux leafless sprig adjacent to the standard 10-leaf configuration. ( Severely lapped reverse die resulting in a missing leaf / ghost stem variety.)
Reverse 3rd Diagnostic : Equally spaced masts (Type C / Large Letters reverse hub diagnostics).
