LOL, you think that any old thing that somebody pulls out of their pocket or hands to a cop in a wad of kleenex should automatically be considered authentic evidence.
Are we trying to solve this case or are you trying your damnedest to get Oswald off on any technicality that you can dream up and btw why wouldn't the Davis shells be considered evidence?
Let's take a close unbiased look at the facts, the murder could have happened anywhere but it randomly happened right near where the Davis sisters lived, so the sisters participation was based on events completely out of their control.
Other eyewitnesses saw a person who they all identified as Oswald dropping shells in the vicinity of the Davis sisters house.
The shells that were picked up matched the revolver that Lee Harvey Oswald was arrested with.
Some alternative scenarios;
The Davis sisters picked up shells that were dropped by the owner of the revolver at some other previous time.
The Davis sisters picked up shells that were fired through Oswald's revolver which were acquired and dropped by the real killer.
The Davis sisters were given the Oswald shells to give to the Police.
And yeah you're right my alternatives are just too far fetched to be believed but maybe you can come up with some other scenario?

Today November 22, 1963 about 1:30 pm my sister-in-law and myself were lying down in our apartment. My sister-in-law is Jeanette Davis, we live in the same house in different apartments. We heard a shot and then another shot and ran to the side door at Patton Street. I saw the boy cutting across our yard and he was unloading his gun. We walked outside and a woman was hollering "he's dead, he's dead, he's shot". This woman told Jeanette to call the Police and she did [sic]. I saw the officer that had been shot lying on Tenth street after Jeanette had called the police. Jeanette found a empty shell [sic] that the man had unloaded and gave it to the police. After the Police had left I found a empty shell [sic] in our yard. This is the same shell I gave to Detective Dhority [sic]. The man that was unloading the gun was the same man I saw tonight as number 2 man in a line up.

Today November 22, 1963 shortly after 1:00 pm, my sister-in-law, Virginia Davis, and I were lying on the bed with the kids. I heard a shot and jumped up and heard another shot. I put on my shoes and went to the door and I saw this man walking across my front yard unloading a gun. A woman was standing across the street screaming that "he shot him, he killed him" and pointed towards a police car. That is the first time I noticed a police car there. I ran back in the house and called the operator and reported this to the police. When the police arrived Ishowed [sic] one of them where I saw this man emptying his gun and we found a shell.
