coins before 1965 are 90% silver ,they damage easy, try hitting another coin on it ....if it leaves a mark there's your proof,
A common test for silver is the "acid test," where a drop of nitric acid is applied to the metal. A positive result is indicated by a creamy white color, which implies the presence of silver. Other tests include the magnet test (silver is not magnetic) and the ice test (silver has high thermal conductivity and melts ice quickly).
The best way to determine if an object is pure silver is to look for markings such as "925" or "sterling" which indicate that the object is made of sterling silver, which is 92.5% pure silver. You can also perform a silver acid test or take the object to a professional jeweler for testing.
No coin is 100% pure silver as 100% silver does not exist, the refining proces does not produce 100% metals. The easiest way to determine silver content is to look up the coin in an appropriate numismatic reference source. which will display metal content and weight for the specific coin you are referencing along with many other details. US collectible and bullion coins are 99.9% pure US circulating coins used to have silver content ranging from 85-97.5% but now are mostly copper with silver cladding.
Pure silver typically refers to silver that is at least 99.9% pure. Fine silver, on the other hand, refers to silver that is at least 99.95% pure. In general, fine silver is considered slightly purer than pure silver.
There's no way i could compare the sterling silver to the test pure platinum. But what i can tell you is that i have tested with test pure platinum and holy smokes! It worked! Now i am set. I could not believe the anxiety i had taking/after the drug screen. I was like "oh man oh man what if". But it worked out for me. Just follow the instructions on the bottle and keep clean a little time prior to taking the test, and it should be smooth sailing. Everyone's different so i wouldn't know the results but i can say that i do believe in test pure platinum!
Silver products can be cleaned with a pencil eraser. Thus, to test a product whether it is made from pure silver, just use a soft eraser. If the item is made from silver, after using the eraser the item should be fine and no extra steps are necessary to clean it.

Yes, you can use a magnet to test silver coins. Silver is not magnetic, so if a silver coin is attracted to the magnet, it is likely not pure silver. However, keep in mind that some silver coins may have small amounts of other metals added for durability, which may cause a slight magnetic attraction.
Pure silver is very rare, so it is hard to estimate how many carats there are in pure silver. It has been estimated that there are about 5 million carats in pure silver.

No it's not pure silver, only 90% silver and 10% copper.
The ASW (actual silver weight) is .18084oz pure silver.
The density of a pure silver teapot should be similar to that of a pure silver bracelet. Both items are made of the same material (silver) and, assuming they have similar dimensions and thickness, they should have a similar density.
About as pure as you can get.
