We showed it to a Hebrew expert (and archaeologist at the same time). He said it talks about the story of Moses, Judaism, then start of Christianity with Jesus, and how some Jews converted to become Christian.
Something interesting he said, then we verified professionally: the leather front and back (bound with the 19 inside sheets with hair) are much older than the 19 sheets; the 400 to 500 year old estimate is for the 19 sheets, not the front and back. All leather.
Also, it was hand written by more than one person.
We asked about value estimate; the expert said: $500k at least.
Nice, right?
