100-ounce silver bars are recognized around the world. Within the precious metal industry, these bars are known as a reliably pure form of bulk silver.

They are also utilized by banks and other financial institutions.


Most mints that produce smaller-sized silver bars also produce 100 ounce silver bars. Popular makers of 100-ounce silver bars include Johnson Matthey, Royal Canadian Mint, and Sunshine Minting.

100 ounce silver bars are what most people picture when they think of a silver bar. Still, they are smaller than many investors realize. Each 100 oz silver bar measures approximately 6.5 inches by 2.5 inches by 1.25 inches. The exact dimensions of the bar differ slightly from mint to mint, though the general size of all 100 ounce bars is fairly consistent.


Weighing 100 troy ounces (or nearly 7 pounds), this is a relatively small, compact way to store your wealth. These are the largest size of silver bar that can still be handled easily; the next largest sizes, 500 or 1000 troy ounces, cannot be easily moved or handled. 100 ounce bars are designed to be easily transported, stacked, and stored. This larger size is often preferred by investors making a significant silver investment because it is easier to move and store a single large bar than several dozen smaller bars.
