4 - The area over the anatomical right eye of the Shroud image (a computer enhancement of the Enrie photograph), showing the letters UCAI and the lituus (the arrow points to the upper third of the critical letter C; the letters are about 1.5 mm high).
5 - A Pontius Pilate lepton ("window's mite") owned by Francis Filas, showing the highly specific lituus, or auger, or astrologer's staff design, the frequent clipped edge from one to four o'clock, and, despite erosion, parts of the letters TIOUCAI (again, the arrow points to the letter C).
6 - The overlapped images, showing the almost perfect congruence of the two indicating that this coin was struck from the same die as the coin over the Shroud image's right eye.
