Buffalo Bill and Annie Oakley Autographed Playing Cards

At a flea market, I recently bought a photograph of Buffalo Bill along with a playing card with a bullet hole through it and autographed W.F.Cody "Buffalo Bill" and stamped Buffalo Bill Cody Wild West Show 1884 on the back.

I also have the same thing for Annie Oakley. Photo and signed playing card with bullet hole and the same Buffalo Bill Cody Wild West Show 1884 stamp on the back.

Any idea what these items may be worth?
