CC is the mark of the Carson City Mint, which operated from 1870 to 1893. Carson City minted mostly larger-denomination coins, although dimes were struck there from 1871 to 1878.
Look on the back of a coin minted during that range of dates. If it has a mint mark, it will normally be on the back. You may also find an S for San Francisco or an O for New Orleans. Coins without a mint mark were minted in Philadelphia; the P mint mark wasn't used until the mid-20th century.
A coin layered in .999 pure silver means that the coin's surface has been covered with a layer of silver that is 99.9% pure. This is often done to give the coin a silver appearance and can increase the coin's value for collectors or investors.
You can determine if a coin is not pure silver by calculating its density and comparing it to the known density of pure silver. If the calculated density of the coin does not match that of pure silver, then it is not pure silver. Density can be calculated by dividing the mass of the coin by its volume.
Silver is an element on the periodic table with the symbol Ag and atomic number 47. A pure silver coin is made entirely of silver atoms arranged in a particular crystalline structure, making it a pure form of the element silver.
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.
When you coat a silver coin with CuSO4 and apply an electric current, at the anode (where oxidation occurs), the silver coin will lose electrons and dissolve into the solution as silver ions (Ag+). This is because silver is more reactive than copper, so it will dissolve to form silver ions while copper will be deposited onto the coin.
Keep in mind that not all silver dollars have the CC mintmark. If your coin does have a CC mintmark it would be above the DO in dollar on the back of the coin.
