Owning silver is one of the most effective ways to diversify any precious metal portfolio, or investment portfolio in general. Silver Bars are the bullion choice for many investors. Silver Bars are produced in a variety of sizes to fit any budget. They are popular because of the diverse designs and sizes, and their affordability as compared to gold bars, which are significantly more expensive. 100 oz. Silver Bars are ideal for investors that are ready to add a more sizable silver investment to their precious metal portfolio, as opposed to silver coins. The 100 oz. silver bar is a standard in the silver industry, typically used for storage, industrial usage, or trading. Mints recognized for their 100 oz. silver bars include the Royal Canadian Mint (RMC), Engelhard, and Johnson Matthey.
