I was just skimming through the 1883 Robert's article, "Marbles and Where They Come From", and saw a reference to "gilded and silvered marbles".
I don't remember registering that sentence before. 1883 struck me as earlier than I last remembered seeing lutz mentioned. But obviously I'm not sure.
Almost every time I go back to the old sources I pick up something new. Why don't I do it more often? lol
p.s. ... what might the "silvered marbles" be? That's not ringing a bell.
