If Christensen actually made these, surely they were not one of a kind or one
of a few. They were quite proud of their creations, making special boxes with American
Agates or Guineas. Would they not have done the same for these types?
Gropper Co. seems to have only packaged slags and swirls. If these Exotics were known to
them, I'm sure they would have been lining up to market them. In either case, some would have
survived from the wild and surfaced by now, in whatever condition.
It just doesn't make sense.
