Yesterday, in his blog, Stephen Jones revisited the topic in a posting entitled, The Shroud of Turin: 2.6. The other marks (5): Coins over eyes. He concludes:

Finally, this is yet another problem for the forgery theory[§14]. A medieval, or earlier, forger would have had to imprint the tiny letters 1.3 mm (1/32 inch), four of which are barely visible, and the rest invisible to the naked eye, on linen, in photographic negative[123], when the very concept of photographic negativity did not exist until the early 19th century[124]. Moreover, these leptons were not identified as being coined by Pontius Pilate until the early 1800s[125], so even in the unlikely event the 14th century or earlier forger knew of these coins, he would have no reason to think they were significant.

But this is so only if you believe that the images of coins are there. I’ve spent years considering this question; I don’t believe they’re there. What people see, I think, is pure pareidolia. (see: Paper Chase: Why There Are Probably No Images of Coins, Lettering, Flowers and Whatnots on the Shroud of Turin). Unless Jones can prove the images of coins are there, he cannot legitimately say that a forger would need to “imprint the tiny letters.”

Jones, to his credit, tries to prove it. He is thorough. His posting is comprehensive with extensive notes and citations. Maybe its me. Can someone explain this to me?

Fifth, the probability that there is a lituus and one letter in the correct position over one of the eyes of the man on the Shroud is 1 in 1.827 x 106 x 6.1389 x 108[122] = 1.1216 x 1015, i.e. 121 with 13 zeroes after it. Therefore the evidence is very strong that there is an image of a Pontius Pilate dilepton minted between AD 29-32 over the right eye of the Shroud. This is true irrespective of whether there is over the left eye the image of one or two Julia leptons, minted by Pontius Pilate in AD 29; and despite the mistake of Filas and Whanger in not realising that since the lituus on the image of the coin in an Enrie 1931 negative photograph over the right eye of the Shroud has a reversed question mark shape, then the Pontius Pilate lepton coin which was the basis of that image must have a question mark shape.
