Weird Times on Instagram: "@sdbullion A strong neodymium magnet is one of the easiest tools to check whether a coin or bar is actually real silver or gold. Pure gold and pure silver are diamagnetic, meaning they’re not attracted to magnets at all, while many fake metals — especially tungsten, nickel, steel, and other alloys — react instantly. When a real silver coin slides down a tilted magnet, it moves slow and smooth because of eddy currents. A fake one either sticks, jumps, or drops too fast.
