Everything looks normal really. The mark around the base where they separate, well, I dont think it means anything. I have those marks on all my brass after the first couple of reloads. The only case head separations I have ever had were from cartridges that were stupidly over loaded with the wrong powder. I have not had anything separate from being over worked. And although I have employed the bent paperclip from time to time, I have never caught anything unusual. (I am not saying it doesnt happen, I am just saying the shiny marks up from the base don't indicate that its going to happen.)
One question: How far down the case are you annealing them?
