<p>[QUOTE=&quot;Boss, post: 395680, member: 15110&quot;]<b>Air Tite</b></p><p><br /></p><p>This thread I started has got me reading everything I could find re coin preservation as the beach air is clearly bad for coins, but sorry not about to move!!!!! I having a debate now with myself re this: how should I best protect my coins in a bad climate? I have already ordered enough AirTites to replace all my Intercepts (to me Intercepts allow too much air in). Ordered (online) albums and boxes both to hold the AirTites as they are too small to strore and don&#039;t want them to get lost (the round shape makes them bad for storage-they fly around). However, it really bugs me that my nonslabbed coins and slabbed coins are physically seperated. Call me weird, but I like orderly storage of my coins in sequence. Thought about buying the Coin World slabs by Amos, that are shaped like PCGS and you can put your own label in . Concerned that they are not airtite enough and I might as well stick with my Intercepts if I was going that route. Appreciate any opinions, especially from those in humid areas with experience with this. Also forgot to mention that I bought Reynolds brand baggies that have a vacuum seal. Called &quot;Handi-Vac&quot;. This little machine sucks the air completely out of the baggy. I put all my albums and Intercept box&#039;s in them. It sucks so much air out it looks like shrink wrap on the albums and boxes!</p><p>&nbsp;</p><p>Found this thread from someone that relates to these issues also (sorry-copied and can&#039;t remember who wrote this): </p><p>&nbsp;</p><p>&quot;I am not really sure of the material of the plastic that is included in the 2x2&#039;s but I&#039;ve had coins in them for well into 30 to 40 year range and no problem yet. However, that may just be a short term reaction. I&#039;ll let you know it there is any adverse effects in the next 100 to 200 years. Same is true of the plastic in my Dansco and Whitman albums. Not sure of the material in the plastic in them either. Now remember that all plastics are composed of synthetic organic materials that are basically non reative with metals unless exposed to a catalyst and proper temperatures to facilitate the reactions. PVC is a stable compound of Poly Vinyl Chloride and will not readily react with coins. In other words if you leave your coins in the plastic 2x2&#039;s and do not expose them to very high temperatures, very high humidity, other possible catalysts, nothing should occur regardless of the plastic materials components. That is usually mistaken on coins as a PVC reaction is usually caused by exposure to extreame heat leaving only a residue of the PVC there which did not react with the matal itself. Other items on coins is usually caused by exposure to the elements of our atmosphere. </p><p>Not to get to tecnical but for instance the oddly misundersatanding of sulfur reacting with copper coins is absurd. The Copper in coins reacts with CO2 in the air first. The resulting compound is what reacts with Sulfites and Sulfates to create the geenish stuff we see on coins&quot;[/QUOTE]</p><p><br /></p>
