Feel confident that the Jeffries and Dempsey are not good. I have about 60 Jeffries examples stored and he did not sign "James J. Jeffries" in any of them, always "Jas J Jeffries". Also noticed he rarely dated his signature which made it harder to pluck out some early ones. Attached a few here, one is dated 1909 but is a smaller file:



Also a few Dempseys dated 1931:
