<p>[QUOTE=&quot;-jeffB, post: 26137365, member: 27832&quot;]I don&#039;t think it&#039;s doing anything as far as oxygen. Only &quot;UV-C&quot; light can generate ozone, and that kind of UV (a) isn&#039;t going to be present unless you&#039;re welding, using sterilization lamps, or doing some tinkering that would give <i>me</i> pause, and (b) wouldn&#039;t penetrate the window on the front of the display unless it&#039;s quartz (it&#039;s probably not).</p><p><br /></p><p>I don&#039;t think lower-energy UV-A or UV-B is likely to do much to coin surfaces, but it <i>can</i> cause other materials in the display to degrade, and some of those degradation products might be gases that can affect coins.</p><p><br /></p><p>It may also be able to yellow the slabs themselves. I don&#039;t know how sensitive modern slab materials are to UV. The labels might suffer as well.[/QUOTE]</p><p><br /></p>
