<p>[QUOTE=&quot;rmpsrpms, post: 2568089, member: 31773&quot;]I have hundreds of OBW rolls that I have kept intact in their original wrappers due to the inherent value of the unknown. I don&#039;t keep rolls from the mint, but I do keep rolls from banks that have the bank name on the wrapper. In fact I collect different banks, and trade folks for ones I don&#039;t own. Indeed you must be careful when you purchase the rolls to be sure they are truly original, and after a bit of experience you will learn what to look for to identify rolls that have been tampered with, searched, re-wrapped, etc. I can examine a roll and with 90% certainty tell you if it&#039;s original or not. That goes up to 99% under certain conditions. Of course it is never 100%, but 99% is pretty good.</p><p><br /></p><p>To address the OP&#039;s question about whether or not to open the roll, whenever I by an OBW roll I go through a decision process to decide if I should open it or put it away as-is. My primary factor is if I believe it is original with &gt;90% probability. If so, then it is really tough for me to justify opening the roll, even if it&#039;s a date that might produce varieties I&#039;m interested in. Note that I only collect older rolls (mostly LWC) so that tends to inform my decision. Older OBW rolls are getting more difficult to come by, so I consider destroying them with the intent of better preserving the coins somewhat foolish.</p><p><br /></p><p>For storage, I simply put them in airtight boxes so they don&#039;t have fresh oxygen around them. I suppose this might increase the concentration of sulphur (from the paper outgassing) but I&#039;m not too worried about the toning impact. A little edge toning isn&#039;t so bad anyway.</p><p><br /></p><p>One final note...opening the roll will expose it to dust and contaminants which will fall on the coin surfaces. This is a much bigger threat to the coin surface than keeping it in a stable situation within the paper roll. I have opened some 1955-S LWC rolls that were so pristine they were essentially as-minted, but that were destroyed by the small amount of dust in my viewing environment. Each coin now has spots forming where the dust landed. It took 15-20 years to see the damage, but by then it was too late. Don&#039;t ruin your coins in the questionable belief that removing them from the original paper and placing them in plastic will somehow better preserve them.[/QUOTE]</p><p><br /></p>
