A few years ago there was a pink sheet stock selling for over $ 100,000.00 a share. It was about a decade or so ago, long before BRK [on NYSE] hit $ 100,000.00 . It was majority owned by a family & of course thinly traded. The family finally bought back the shares [privatized it]. They were involved in plumbing fixtures, it might have been Kohler [maybe I mispelled that name].
