Hi Sebastiano,
Agree with Tom's comments.
It must be remembered that silver is a soft, ductile metal and any harder, sharp object that strikes the surface, can produce a shaved, lifting effect, giving the appearance of, perhaps, a coating.
As Byron remarked, the marks do look authentic, but I'm not at all sure of your attribution to William Bayley, it is a difficult one and it would be good to hear the thoughts of other members.
Regards Trev.
