Very interesting. I guess that pushes the known release date back to 2004? I can only imagine how many of these are really out there now, considering the silver examples I handled were probably recently made. Funny thing too - the gold pieces, from those who have handled them, all describe them as looking like actual gold, which they may be. And the silver ones I've had, oddly enough, do look like silver with some gilding. Maybe these were originally intended for high-end jewelry and needed to be of precious metal?
