No. Most of the modern fake silver bars and rounds are NOT magnetic. They are copper or brass plated with a thin layer of .999 silver, often enough to fool a quick surface acid test. There are fake Engelhard Prospectors, fake Sunshine bars, fake Canadian Maples, fake Pan American bars, and fake generic US Flag bars, just to name a few. They are very close on weight, usually within 0.5 - 1 gram of a troy ounce, and they ARE marked ".999 fine silver." They don't ring like silver, and you can tell the difference if you have a good one to hold next to them (details are a little off, with some the thickness and/or reeding is off), but on their own many of them are pretty convincing.
