Eldred G Smith was the last functioning Presiding Patriarch of the Church and as such was a direct descendant of Hyrum, the brother of the prophet Joseph.
While at BYU one Sunday evening I went to a fireside where Elder Smith was the speaker. I was fascinated by all that he knew and by the things he talked about that I had never even read about. Of course as a relatively new convert (this was after my mission, so I had been a member for about 4 years), all this stuff that everyone else had grown up with was intriguing.
I remember he was talking about the box that Joseph had commissioned to keep the plates in and safe while he was translating them. Joseph described it as being a wooden box, or chest, with a lid and a lock.
Then Eldred Smith reached down under the podium, brought something out and put it down in front of him and declared "This is the box".
I was so moved by the experience that I have never forgotten it. I even went up afterwards so that I could see it. It was plain and worn with age. And it had held the golden plates.
