A hundred troy ounces of .999 fine silver, 3.11 kilograms, in a cast Johnson Matthey bar. JM's Canadian hundreds carry the diamond JM logo with crossed hammers, 100+ OZ, and 999+; some carry a serial number and some do not. Johnson Matthey, the London refiner founded in 1817, made bars for 162 years and sold its gold and silver refining business to Asahi in 2015, whose hundreds are the same bar with a new logo.
A cast hundred is a brick with a rippled top. Expect handling marks, and expect the bar to have been tested before it reaches you.
