Using current technology in microscopic, chemical and age dating, APS analyzes and documents artifacts and samples represenative of artifacts to determine authenticity.  APS has analyzed stone and gold artifacts, stone structures and associated documents to each.  

Questions we ask:

  • Is this artifact/structure's form consistent with the times?
  • Is the material used consistent with the times?
  • Does the weathering profile match up with the suspected age of the material?
  • Does the location of where the material was discovered make sense? Was that material available?
  • What sort of documentation can be provided?
