EXTREMELY FINE APPEARANCE. A RARE EXAMPLE OF THE 30-REIS SEMI-XIPHAPOGOS, WHICH SHOWS THE INTERPANNEAU DIVIDING LINE AT BOTTOM.
Bull's Eye stamps from the composite plates that show the diving line between panes are called Semi-Xiphopagus. Such stamps are especially desirable because they can be immediately recognized as examples from the composite plates without the need for plating (the two known Xiphopagus multiples are, of course, the se-tenant pair and strip of three). The 60r Semi-Xiphapagus stamps come from the top or bottom of the middle pane (twelve positions). The 30r and 90r are rarer, because they can only come from one row (30r bottom, 90r top, six stamps positions each).
