From time to time I see these on ebay. Typically they come with a copy of the original document that was butchered to make them.
I guess I am not asking thoughts on the desecration of the historical documents, or even really the cost associated, however are there any opinions as to the validity of the pieces? Do they appear authentic fragments of handwriting? For someone who cannot spend $10-$15K for a signature, they might prove to be a reasonable way to obtain something.
