The internet has been flooded by similar objects and other types of "Jewish" books, and there have been additional smuggling attempts. These fake objects are also for sale in the Jordanian market, where such books are offered for sale to tourists.
The Antiquities Theft Prevention Unit (ATPU) of the Israel Antiquities Authority (IAA) noticed a massive increase of the phenomena since the beginning of the civil war in Syria. During the last five years, the ATPU has been dealing with, at least, one book offer each week. Most of the books' background stories talks claim that it was found in Syria under synagogue remains or in a secret cave in an unknown archaeological site.
This was partly based on destruction of Jewish temple destruction at The Jobar Synagogue was an ancient synagogue complex destroyed in May 2014. Also known as the Eliyahu Hanavi Synagogue it was situated in the village of Jobar. The items was looted. but contrary many scam counterfeiters. Its contents was photographed and cataloged.

Many times, the owners of the books also state that the items were already smuggled out of Syria to either Jordan or Turkey by Syrian refugees - to make it sound more available.
The books are either made of lead, paper, parchment or another material. They are all imprinted with Jewish motifs, mostly copied from known ancient Jewish coin motifs: Menorahs (6-branched candelabrum), palm trees and branches, Shofar (ram's horn), and also with a Star of David
(which incidentally only became a Jewish symbol only around the 18th century AD). forgers don’t understand that the symbol that appears on the flag of the State of Israel is a modern one, so their promises that the artifact is thousands of years old doesn’t even hold up to the simple test of looking at the cover of the book being offered for sale.
The lead-made books are also imprinted with text: In the lead books the text is in gibberish, written in a mix of ancient Hebrew, Greek and Latin letters with no actual meaning. In the paper and parchment books the texts are written only with Hebrew letters - usually modern letters, with some actual words but with no logical sentences and or syntax. Most of the books are heavily decorated, many times with gold-like Jewish motifs to increase their attraction.
So having all the above elements and having mix of suspect out context coins 1st and second century coins to give a contextual age to fake manuscripts.
Interpol has purple notice of such alleged artifacts.
