Are these all personal finds?
I ask because all of the Celts look like the blades have been put on recently. The very large piece on the bottom is a Roller Pestle. The notched piece is very unusal and could be an Atl-Atl weight. The drilled piece looks to be a salvaged Pendant or Gorget, especially with all the tally marks on it.
The thing is though, unless these are all personal finds I would tend to be a little suspect of all of them.
