<p>[QUOTE=&quot;krispy, post: 1480531, member: 19065&quot;]Managing or controlling the environment where we keep our collections is not that difficult nor costly. The cost comes IF damage occurs and we need to replace something or find conditions compromised the condition and the piece(s) in our collection become less appealing or valuable when resold. </p><p><br /></p><p>Many collectors do just fine to control the environment where they store items by using silca gels that can be replaced or recharged and store things away from exposure to light, and fluctuations of hot/cold and swings in humidity. It is more challenging in some places due to heat and humidity, say in the southern climate of the US, or very arid climates. The materials you used to encase a collection should be of archival grade and we should not allow overly cramped storage conditions to exist nor materials that have dyes, synthetics that break down or gas-off over time, as these things can affect collections, be they paper or coin.</p><p><br /></p><p>Generally speaking my notes are individually stored in archival grade mylar sleeves or TPG holders (I have both PMG and PCGS holders). The only other paper or boards I keep around my notes are 100% rag paper, those that are dye free. I use some Cranes &amp; Co. envelopes with no glue seals for some things. I also employ buffered acid-free interleaving tissues for some paper items, which is a special archival paper (very affordable) that is embedded with Calcium Carbonate to help neutralize acids that can attack paper, thus extending the life of paper collectibles. All plastics (other than mylar or stiff acrylic holders) and things like rubber bands and any sort of wood are not allowed near my collection. The notes are kept in a bank SDB, at a location I selected because the branch monitors and regulates the humidity in the vault rooms to a consistent level. Inside the box, I keep small silca packs and change these according to the suggested times they should be replaced. I do as much as I can to protect and preserve my collection.</p><p><br /></p><p>Of course humidity is natural and it has a natural effect on natural materials. We understand what is acceptable and we as collectors do the best we can to preserve our collections by storing things to the best of our ability and affordability. I&#039;m sure that some collectors who strap search circulation finds don&#039;t individually insert every note in to mylar holder and follow all the rest of what I mentioned, and that&#039;s perfectly fine. I am more focused on mentioning how subtle environmental factors can have an effect over the long haul and how rarer and more valuable notes should be minded in our care.[/QUOTE]</p><p><br /></p>
