Silk is even more priced than paper (though it depends on paper, I saw some hand made sheets for kana, A3 size, 250$ each), as painting/writing on it is much more expensive. Another thing is that one needs to be really skilled with a brush to write on silk. Its surface and ink blur abilities make it really difficult to write on. If the scroll is from the collector it means that it is most likely authentic.
