A hundred troy ounces of .999 fine silver, 3.11 kilograms, from the Royal Canadian Mint. The front carries the Mint's crowned maple leaf hallmark ringed by its name in English and French, 100 oz t, FINE SILVER 99.9 ARGENT PUR, and a serial number set in a raised rectangular panel; the current version is a cast bar about 184 by 81 millimeters and 21 thick with a rippled surface. Older bars from the Mint vary in finish, and the one you receive depends on what is in stock.
A hundred ounces is the first size where you lift the metal rather than hold it.
