<p>[QUOTE="Just Carl, post: 528550, member: 4552"]Ouch. I think you need to do a little more research. Moisture, water, aqua is not really H20. It is in reality H(OH) otherwise known as Hydrogen Hydroxide. The OH radical is the stable molecule but the loose H atom is what redily reacts with substances. Water is also known as the Universal Solvent since it will dissolve almost everything given time. Even over time it will dissolve the glass it may be kept in which is basically Silicon Dioxide. </p><p>However, corrosion, verdigris, toning, tarnishing or other terminologies to describe the combining of gasses with metals is not transferrable like a bacterium or germ or virus. Maybe someday, someone will find out Verdigris is really alive and attacks coins just to get Numismatist irritated, but till then, it is moisture, Oxygen, Fluorine, Chlorine, etc that has those messy effects. As long a those are present, the same will happen to the same metals. </p><p>As an example if you live in a house and there is Copper piping there, you may have noticed that too is or has turned greenish in places. Usually this happens in areas where there have been steel mills or power stations that burn Sulfur Rich Coals. Although minor the SO or SO2 in the air mixes with the H OH forming Sulfuric or Sulfurous acids and attacks Copper to form the CuSO3 or 4 greenish crystalizations. Placing another piece of Copper next to or even on that pipe will not transfer such corrosions but in time the same contaminated air will effect that new piece of Copper the same. </p><p>Or maybe corrosion is alive and moves to different coins to get us mad.[/QUOTE]</p><p><br /></p>
