I suppose you can still find them in some stores, but they seem to have fallen out of fashion. I’ve heard varying opinions of their safety, I eat them but I’m a risk-taker by nature. YMMV.
This site calls them Dragees and says “These gold and silver metallic candy balls do much to enhance a confection. They are non-toxic, however, the Food and Drug Administration recommends that they be used for decoration only.”
