<p>[QUOTE="Just Carl, post: 423038, member: 4552"]Absolutely not true. Note the tern Oxidation. This indicates the combining of Oxygen with other elements or compounds. Also, note the air is full of Oxygen. As long as Oxygen can come in contact with many, many substances, it will react and combine to form other substances such as toning, tarnishing, corroding, etc. Also, note that almost all fires are nothing but rapid Oxydation. Usually Carbon based substances, wood, combining with Oxygen. </p><p>In reality storing a coin in water, distilled water of course, will not do anything to the coin. Actually better than leaving it laying out in the open where Oxygen can attack the metal. </p><p>Silver usually combines with Nitrates to form what we see as TARNISHING. Silver also combines freely with Florines, Sulfates, Sulfites, etc. </p><p>The coin in question appears to have corrosion of some type, and the corrosion may be a combination of substances and the actual metal of the coin. Removal would also take some of the coin with it. </p><p>Not a good choice.[/QUOTE]</p><p><br /></p>
