Hi Reichrev,
It sounds as though the primer was still live, indicated by the anvil and disc. That little disc by the way is the priming compound. The small amount of powder in the primer cup indicates the cases were live at one time and someone else had emptied the powder out, except the little that made it's way into the primer cup.
As they are they are pretty safe, unless someone tries to fire them in a firearm, which hopefully would only lodge the bullet between the barrel and cylinder and lock it up. If you loosened the anvils taking them apart, leave them out when you put them together, and the same goes for the disc. This will make them even safer.
