I got lucky with the one that i did. It was interred in a wall for like 20 something years. Husband wanted her cremated, at her time of death the family wouldnt allow it and it was her dying wish. So we had to remove all the metal from the casket, huge wooden casket, while she was in there. Pretty crazy, pretty cool. You could see the crack in her skull that killed her. Everything was so desicated there wasnt really any smell at all.
