It is my understanding that computer enhanced images of the face show Roman coins were on his eyelids. Also as I recall, that there were spores of Mideastern plants on the Shroud.
The un-peer-reviewed claim is that there are Leptons minted by Pontius Pilate in 29 AD on the eyes. These leptons are unique... and until the research on the shroud, were unknown. They contain a misspelling of the word Ceasar. It was thought this was an error on the part of a Shroud hoaxer, but to date six Pontius Pilate Leptons have been found with the same error. This has been seen on the Shroud by some researchers under enhancement but not by others.
There are spores of plants native to the Jerusalem area that have been found on the Shroud... as well as spores from Edessa, Turkey, Constantinople, France, and Italy. These results have been peer-reviewed. The problem with using pollen evidence is that pilgrims came from all over Christendom to see and touch the Shroud... and it was not thought necessary in antiquity to wash and wear latex gloves when handling it. The Pollen may be transfers from such visits.
There is also a light dusting of a very rare form of Calcite, Travertine Aragonite. The microchemical analysis of the dust, found both on the back of the dorsal image portion of the Shroud and also in the area on the front where the feet rested, match this rare form of calcite that is currently known only to exist in one area of the world: Just outside the Damascus Gate of Jerusalem.

Indeed. Thanks for the information!
