No, you do not clean coins. Cleaning coins will only damage their value. If you feel you must clean a coin, take it to a coin dealer and see what he recommends to clean the coin, however, they will recommend you not to clean it. Coins potentially worth hundreds of dollars have been brought down to selling them for scrap because people have cleaned them! Do not clean coins!
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.
One common method is to check for mint marks or engravings that indicate the coin is made of silver. You can also use a magnet – silver is not magnetic so if the coin is attracted to the magnet, it is not silver. Lastly, you can consult a coin expert or use a testing kit specifically designed for identifying silver coins.
Sterling Silver is very easy to test. Silver plated brass, nickel silver or low quality silver alloys will turn green when a drop of Nitric acid is applied. Sterling will turn a creamy color. Testing kits made specifically to test sterling silver are available from many jewelry supply companies.
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 it's a U.S. coin the denomination and date are the best way to determine. Dimes, quarters, halves, and dollars minted before 1965 are 90% silver. Among old denominations, half-dimes and some 3¢ coins are 90% silver as well. Half-dollars from 1965 to 1969 are 40% silver. Dimes, quarters, and dollars minted in 1965 and later have no silver in them. They're either cupronickel or (for dollars from 2000 onward) brass. Cents have never been made of silver. 1943 cents are steel. Nickels made during WW2 are 35% silver. Foreign coins may be much more difficult to deal with, but again the date and denomination are the places to start.

The short answer is, do not clean your coins.WARNING - There is no way you can clean a coin without damaging the finish and reducing or eliminating any collector value it may have.If your coin has any collector value or you propose to sell it, you will damage the finish or lustre of the coin by cleaning it.The British 1942 Florin has a 50% silver content. Some coin catalogues suggest that you might use soap and water very carefully on silver coins or, that there are professionals capable of cleaning coins.If your coin has no collector value and you would just like to clean the crud off and make it shiny again, use a jewellery cleaner (which contains acid).

Half dollars were never made of solid silver. It's far too soft to use in a circulating coin. US halves were made of 90% silver up till 1964, and 40% silver from 1965 to 1970. Please post a new question with the coin's date for more specific information.
Assuming it's a standard circulation coin, it has no silver. France ended the use of silver for circulating coinage in the early 1970s.
lemon juice will clean a coin great. But don't use it if the coin is valuable or collectible, that will lower the value. hope this helps. Brian
This isn't any standard US coin and I doubt if many other countries use either of these symbols. Can you tell us what other writing is on the coin - perhaps it says ".999 Silver"? It is a privately minted silver round. Its value is based only on the silver it contains -- about $18.00 as of mid-2008
