Any heavier - it probably is fake, any lighter and it probably is fake. Hold your silver piece at a 90 degree angle with magnet at the top and let the magnet slide down the surface. If it falls off or slides rapidly, it's probably fake.
If it sticks, it's probably fake. It should just glide down the piece all most purposely (sort of slow and controlled, but not too slow).
Practice a bit you, will get the hang of it. Hold a piece of known silver on the tip of your finger and, balancing it, take another piece and give it a little tap.
You should hear a nice bell ringing tone. If it clinks it probably isn't real. These tips should keep you relatively safe! 9999 - pure - silver- collectible - limited - ssg - exclusive - democrat - republican - dnc - rnc - bullet - shield - rare - stacking - stacker - graduation - trivium - freedom girl - standing - southern - confederate - anarchy - anarchist - silver coins - 2015 silver eagle - rare coins - ruthenium - nude silver - pirate. 999 silver coin - hammer struck.
