The U.S. Half dollars,quarters and dimes dated 1964 or before are 90% silver. And 1965-1969 half dollars are 40% silver. With all dollar coins from 1878-1935 are 90% silver.
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.
No circulating US coins were ever made of sterling silver (0.925 fine). US dimes, quarters, and halves minted up till 1964, and dollars up to 1935, were made of coin silver which is 0.900 fine.
in order to tell for sure, you would need to take it to a coin specialist. most coins now are a mix of zinc and copper. if your coin truly is silver, it is probably very very old and worth a good amount of money.
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
It is. All half dollars made in 1964 and earlier are 90% silver.
By the mint mark on the reverse of the coin, but silver dollar coins with no mint mark are made in Philadelphia
Assuming you refer to the 1981 British 25 Pence coin (Crown), it is made from a copper-nickel alloy. If you have a sterling silver Proof coin, it will state somewhere on the packaging that the coin is made from sterling silver.
If it is a "Silver" coin, it will say so on the case it came in.

The U.S. has made many silver coins. Please be more specific and post new question.
A genuine silver coin produced by the Royal Mint will be in protective packaging indicating what the coin is made from. It should also include a certificate of authenticity.
Such a coin is not an official mint product and therefore it is impossible to tell what it is made out of. To find out what it is made out of, either go to the manufacturer's website or ask a reputable coin dealer or jeweler to see if it is silver and what purity of silver it is.
Nothing most likely. It is not an official mint product, it has next to no collector demand, unless it is made out of silver it is worthless. If it is made out of silver it is worth the price of the silver in the coin. Since non-mint products have no set composition, I cannot tell you what it is made out of and how much silver (if any) is in the coin.

The easiest way is to compare the coin to a known one and look at the date, most of the time that will tell you if it is silver. For example, a US quarter dated 1964 is silver, a US quarter dated 1965 is not. Most of the time that can tell you about the coin. The next is to make sure the coin isn't counterfeit, the easiest way is to check the diameter, thickness and weight. If they aren't like the genuine coin, it is likely the coin is counterfeit and made out of an inferior metal.
A silver pattern crown coin is a British coin that was produced between 1707 and 1965. This coin is made of silver and has a profile picture of Queen Victoria on it.
One way to know a coin is not silver is to check it with a magnet. If the magnet sticks to the coin, it is not silver. If the magnet does not stick, it still might not be silver. You can test it, but to do that you need a test kit.
