re: What is the rarest thing you have ever seen in your life?

Meteorite in private tour at Smithsonian . Had to wear glove to hold any very rare one of a kind. Very cool stuff my brother paid good amount at a charity auction. He was allowed to take 6 total people. His family of four and we went to the start to have our two kids to go with them. The scientist giving tour said y’all can come also.
Was a couple hours long and was all behind the doors stuff. Some that has never been displayed.
