By knowing that the coin would be affected by m leave it on water easuring the changes if you
I think you would have to be a physicist to do that. It would be easier to identify the coin by nation of origin, date and denomination, and a coin guide book will help do this, and the book will tell you what metal the coin is made from.
You can look on the rim of the coin and if there is no brown on it it is silver. If the coin is silver looking on the rim then drop it and listen for a high pitch cling sound which is another way to identify it.
If you can bend them with your teeth, it is a fake coin.
It is. All half dollars made in 1964 and earlier are 90% silver.
Silver dimes, quarters, and half-dollars sound different when dropped than their modern counterparts. Also, if you look at the sides, you will not see any copper on a silver coin, but you will on a modern coin. Another way is to look at the date on the coin.If you are ok with scraping the coin on a testing stone, there is an acid test kit you can get to be sure it's silver.Another trick I've found is to put your coin, and another coin that you know is silver, under a sheet of tissue paper. If both coins "shine through" the tissue equally, then your coin is likely silver. If yours seems dull or dark next to the silver one, then it is likely NOT silver.DanUser:WorkingMan
Divide the mass by the volume to calculate its density. If its density isn't the same as an equal amount of pure silver, the coin has some other metal in it.The density test can be fooled if the coin was adulterated with other metals that average out to the same density as silver, however.

The density of pure silver is 10.5 grams per cubic centimeter. If you have the exact volume of the coin in CCs, you can calculate the weight that it would be were it pure silver. If it differs substantially from the calculated value, it is an alloy.
The idea is to divice the mass by the volume, to get the density. Then compare to the density of silver.The idea is to divice the mass by the volume, to get the density.

do you know how much money a silver 1872 dollar coin is and a 1922 silver dollar coin
