How many ounces of silver in a 900 silver quarter?

Answer 1

The coins only weigh 12.5 grams to start with, so they can't have an Ounce of silver in them. 90% silver halves contain .36169 of an ounce of silver. 3 would be just a little more than One Ounce.

Answer 2

Quarter's don't weigh an ounce to start with, so it can't have any ounces of silver in it.

As per the US Coinage act of 1792, the silver quarter was to be made of 6.01 g pure silver or 6.74 g standard silver. Standard silver is an alloy of 89.2% purity.

A troy ounce is 32.15g, so yeh there is much less than an ounce in a quarter.

Modern day quarters vary slightly in weight from the original Act but not enough to make any significant difference to their worth.

Answer 3

One silver dime contains 2.25 grams of silver, which is 0.072 troy ounces.

Answer 4

about 3 per ounce of silver
