John, each chip has a hole drilled into it, presumably reducing its collector value as an individual piece to close to zero. Taken as a whole, the necklace reminds me of Gypsy folk art of Europe where people used to make similar necklaces of gold and silver coins. I kinda like the concept, although I wouldn't recommend drilling holes in, say, the Plaza's Oscar Goodman chips to make similar artwork. Well, at least not until next year or so.
