I was just watching some interesting videos about artefact discoveries in your property or home.
What came to mind was interesting and depending on what state and country I presume the law would be different, but my question is.
If you found and dug up some milllion years old worth of historical artefacts in your home made of diamonds and gold, would you sell it? Keep it? or surrender it to the authorities or archaeologist?
If you dig up ancient bikie artifacts, then put them back and keep your mouth shut.
