Die A (Die I) vs Die B (Die II)
Cyprus 1882-94 Scott 19 1/2pi green & Scott 19a 1/2pi green
Both Watermark "2"- Crown and C ABlack arrow: The vertical line of color stops at the sixth line of horizontal shading of the neck for Die A; eighth line for Die B
Red arrow: A small horizontal dash line in the jewel for Die B; no such discrete dash line for Die A
Blue arrow: Seventh and Eighth horizontal groundwork lines tend to converge at the head for Die A; remain parallel for Die B. In general, the horizontal groundwork lines vary in thickness, and are all not parallel for Die A, while the groundwork lines remain of uniform thickness and parallel for Die B.
Green Arrow: Dark vertical shading separates out the bun from the front hair in Die A; while there are white strands of hair found instead in Die B.
Orange Arrow: White space in the coil of the hair is pin head shaped in Die A; while the white space is oblong and a line of color divides the left end in Die B.
Because of cancel marks,a particular sign may not be obvious for an individual stamp (as is demonstrated here), but another sign may be obvious and clear.
Ken11- Your stamp is Die A (Check out the signs!).

But the identification still requires watermarking.
