Hello.
So this is a previously asked question with no answer given yet I believe.
I visited the museum today and some of the relics are old and very well conserved that raised some questions.
Is there any historical and scientific explanation about letters and other objects ? Is there known c-14 testing of the objects ? Are all of the relics or some of them hoaxes ? (This paragraph was taken from an old thread)
Edit : these relics https://en.wikipedia.org/wiki/Sacred_Relics_(Topkap%C4%B1_Palace)
There is no photograph. Without some context or additional information, there is no way to answer your question without going to the museum.
