I buy from JM Bullion too. I've been very pleased with them. You can also quickly do the ice test to see if your silver is real. Take two pieces of ice. Put them on a flat surface. Put the silver coin on one of the ice cubes. If the ice cube with the coin melts faster than the one without you can be pretty sure you have a silver coin. Silver is a metal that naturally conducts heat thus melting the ice faster than just a sitting piece of ice. I stay away from Ebay too risky. They are getting very good at making fake silver coins right down to the weight. Tooooo risky.
