what does it mean when a piece gives a weight such as 10oz?

i come across pieces of metal tha t look like silver which might have weights stamped on them such as 10 oz or 80gr. does this mean they are silver ?

Thanks for joining us on silver collector…usually those marks are for the volume of a vessel - i.e. how much liquid it will hold, not the weight.

Uncle Vic - back from NYC with some good silver from the flea markets…been a long day flying, will report on the trip tomorrow on the American silver section.
