Sue, I was half serious, wasn't trying to be too smug. (Just a little bit maybe.... ) Sulfides, along with many handmades, have fallen into disfavor with many collectors. I've held onto the human figure one I have, plus a nice eagle sulfide. I've seen pretty nice sulfides get ignored at live auctions, although regular antique dealers like them because they can safely identify them. Not that there have been any live auctions with marbles in this neck of the woods for eons.
