Front and back pics of two small button size items.....not sure what they are. One looks like brass or Tin and the other is a small piece of Lead.

flattened bullet or a lead bale seal & a knock out from an electrical box ?

The back of the lead disc shows that it is the lead cap from a roofing-nail. That type has existed for more than a century and is still being made today, so there's no way to date yours.
