The analysis of impressions on the ocular areas referable to forms that can be usually found on the sides of roman coins is fundamental to study the Shroud.

The proof of the real existence of coins’ impressions on the image would sure enough be a further confirmation of the cloth authenticity; of course, it is very unlikely that while creating something artificial a medieval copyist could have inserted such a particular, not visible information associated to a then unknown practice. Some historical-archeological researches refer to the funeral practice of putting little coins on the corpses’ eyes to prevent the lids to lift or simply as a simbolic ritual act.

In 1954 the theologian father F.L. Filas from Chicago started to look for coins’ impressions by a series of studies both in the photographic and numismatic fields. Starting from a copy of the 1931 original plates by G. Enrie, father Filas announced he had located on the right lid some impressions that were very similar to those on a side of a coin, a "dilepton lituus", presenting the symbol of the lituo, a kind of crosier surrounded by the greek inscription TIBEPIOY KAIAPO. This coin dates back to Tiberius time and, reading the date on its back, it can be deduced it weighs no more than one gram and is nearly 16 millimeter in diameter; some copies with mint mark warpages and different inscriptions were found as well.

Some copies clearly present the inscription TIBEPIOY CAICAPOC where the latin C, which has the same pronunce, replaced the letter K whereas also the letter S easily becomes a C.

The impression can be esteemed at its best by observing the cloth photo negative as shown in fig. 8.

One can also recognize a mould reminding of a question mark surrounded by the letter Y that could be the final letter of the word TIBEPIOY, separated by the letters CAI which are part of the word CAICAPOC.

In fig. 9 you can see the result of having submitted the particular photo negative to 3D processing.

As one can see, a baton in the shape of a question mark can be made out and, next to the upper left side, there are some structures one can connect with the letter Y distant from the letter C and followed by the letters A and I. The photo negative through 3D processing brings out a form of a reversed baton and we can therefore guess the coin had to represent a question mark. It is therefore necessary to suppose the existence of a coin with a reversed baton specular to that considered by Filas.

Mario Moroni, a numismatic who has some copies of it, verified the existence of a coin of the time with a baton in the shape of a question mark on one side (fig. 10).

It is a backwards "dilepton lituus" issued by Pontius Pilate in the year 16 of the reign of the Emperor Tiberius which corresponds to the 29 A.D..

The research of a probable presence of a coin impression on the left lid has been taken into account contemporaneously to the research about the right eye. However, by observing the bidimensional and three dimensional image, there is no form that can be connected to a coin impression.

On the contrary, the analisys of the eyebrows arch highlights a strange bulge in the three dimensional image that leads to believe in the presence of a foreign body. Prof. Nello Balossino and prof. Pierluigi Baima Bollone processed the bidimensional image of this area highlighting the presence of signs from a "lepton" and; in particular, the observation of the bidimensional image (fig. 11) allows to glimpse the forms of a structure reminding a cup and three letters that can be interpreted as the inscription "LIS". The numismatic experts well know these three letters mean "sixteenth year" the "L" meaning year, the "I" meaning ten and the "S", six. It is therefore the sixteenth year of the reign of the Emperor Tiberius that corresponds to the year 29 of the Christian era. This is the coin’s coinage date, a "lepton simpulum" (fig. 12), and many are the copies with a ritual cup on one side, that is to say a "simpulo".

This kind of coin were around in jewish markets and had a small change value. The coin had the "simpulo" at its centre and also the inscription TIBEPIOY KAIAPOS and the final acronym LIS as expression of its dating.
