<p>[QUOTE=&quot;desertgem, post: 1583982, member: 15199&quot;]That is normal preservation for an automobile paint job, where as it is not for coins. Otherwise an acrylic plastic coating would do even better at protection, but&nbsp; would never satisfy a coin collector. BU coins fresh from the mint have already started reacting with the environment causing a thin acceptable patina to form. If the coin is kept from moisture, plasticizers, and tainted air, the patina should protect it for a lifetime or more. With the normal conditions, enough reaction can occur to change the coin from Red to Red-brown to Brown, so if one wants to protect against that, my recommendations would be to store in a vacuum, or store with desiccants and&nbsp; bright copper sacrificial cents (cheap),</p><p>or with Intercept products ( relatively expensive). Desiccants, sacrificial cents, and intercept products have to be changed over time as their reactants are used up. </p><p><br /></p><p>Jim</p><p><br /></p><p><br /></p><p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
