No. Silver coins are not magnetic. Pure silver falls into the category of diamagnetic materials, which means that it is repelled by a magnet.
This silver property can actually be used to test the authenticity of silver coins. If a silver coin or bar sticks to a magnet, it is likely not genuine.
That being said, it’s important to remember that while silver itself is not magnetic, fake silver coins could be made from other metals that are. While a magnet can help identify some counterfeit coins, it should not be the only test you rely on.
