<p>[QUOTE=&quot;GDJMSP, post: 835269, member: 112&quot;]leeg - </p><p><br /></p><p>Do you have any idea of age or origin of those documents you posted ? I ask because they seem to be based on very old ideas. I would guess they are a minimum of 50 years old and probaly quite a bit older. Most likely, over a century old. </p><p><br /></p><p>The use of brushes on your coins, storing your coins in sulphur laden paper envelopes. You&#039;d be hard pressed to find anybody, outside of the EAC, who would recommend either of those practices. And I suspect you&#039;d find that many current members of the EAC wouldn&#039;t recommend them either.</p><p><br /></p><p>The one thing out of all of it that you probably would find recommended would be the use of xylene as a cleaning solvent. And of course those that still stick with the idea of applying oils to their coins.</p><p><br /></p><p>This is the point I have been making all along. These ideas come from ages past when people didn&#039;t know what they know today. And eventually they will slowly fade away and disappear from use as people become more and more educated and their desire to own original, unmessed with, problem free coins increases.</p><p><br /></p><p>Just like the idea of using lacquer to protect your coins faded away. You&#039;re a great example of that with coin you did such an excellent job on. </p><p><br /></p><p>There was a time when using that lacquer was &quot;the&quot; thing to do. Recommended by virtually everybody who was anybody. But look at that idea today. </p><p><br /></p><p>All of these ideas and methods on what to do to protect your coins, particularly copper coins came to be because people could not find any way to store their coins and protect them. So they used lacquer, varnish, shelac and the like. They used this oil, that oil and companies struggled to find a new and different oil, one that worked better, and shhhh - careful now, somebody might hear :secret: - did less damage than other oils. That&#039;s why Coin Care and Blue Ribbon were invented you know - because they did less damage than other oils. But everybody that uses them forgets that.</p><p><br /></p><p>But today, we have learned new things. We have new materials to store our coins in - and protect them from the elements, the ravages of corrosion and the like. We have completely inert, hard cased coin holders that didn&#039;t exist 50 years ago. Most didn&#039;t exist 25 years ago. These new coin holders do not trap moisture. They do not allow the coin to move around like they do in a flip or an envelope. They do not allow the coin to become scratched or damaged like those in a coin album. These new holders we have today protect the coins, and protect them quite well.</p><p><br /></p><p>Furthermore, we have also learned about keeping our coins in cool, dark places. Places where the humidity is kept low by using rechargeable silca gel packs. </p><p><br /></p><p>Today we have the methods we need to protect our coins without using oils and lacquers. Methods that those in the very recent past did not have. And we have learned more about chemistry. Learned that these previously trusted and relied upon methods not only can be harmful to our coins - but will be harmful to them. It is only a matter of time.</p><p><br /></p><p>So I stress to you, and all others - it is time, past time, to put away these antiquated ideas and methods of protecting your coins. And use the knowledge that we have today.[/QUOTE]</p><p><br /></p>
