<p>[QUOTE=&quot;GDJMSP, post: 761505, member: 112&quot;]OK dayriser, let&#039;s take a few of your points. About copper being the most reactive of our coinage metals - I will grant you, manganese is more reactive than copper. I had not considered the most modern of our coins, meaning our current dollar coins. But of all the coins minted over the centuries - the modern dollar might comprise something like .0001% of the total. I think I&#039;ll stick with my original comment. And no I didn&#039;t do the math, be my guest. You&#039;ll likely find out that my number is too high.</p><p><br /></p><p>Now let&#039;s talk about finding a way to protect a coin to a reasonable degree. Yes, in today&#039;s world we can do that, to a reasonable degree. But we, and when I say we I mean coin collectors, cannot stop it. You say that airtight containers have been around for thousands of years - then why is it that even in today&#039;s world we collectors still do not have one ? Yeah, there are some scientist that probably have one, but coin collectors don&#039;t. They don&#039;t have one now and they certainly didn&#039;t have one a hundred years ago. You name me the coin holder that you think is airtight - please.</p><p><br /></p><p>Then would you please point out the sentence where I said that dipping hurts the value ? I can&#039;t find it. Yes, I will agree that improper dipping hurts the value, but a properly dipped coin can even increase in value. If you took the time to go back read all of the thousands of posts I have made on this forum you will find that I have said the same exact thing on many, many occasions. In my comments in this thread I was merely pointing out that the vast majority of older coins have been dipped and the reason that we know that they have been dipped.</p><p><br /></p><p>You say that the use of superlatives is not wise, I agree with you on that point. So I suppose I should have said something like - any and all coins will begin to tone from the moment they are struck - unless they are protected from the air. That&#039;s all it takes - exposure to the air. But then that brings us back to your comment about airtight containers doesn&#039;t it. </p><p><br /></p><p>You mention jars, well the best jar storage system that I know of would be the venerable Mason jar, with its sealable lid. Yeah that was a good one. As a child I ate many a meal from the foods stored in those jars. Problem is, there were just as many that had to be thrown out, because the jars were not airtight. They allowed air to seep in and spoil the food. So I guess I&#039;ll wait for you tell me about the myriad airtight containers that have existed for thousands of years. Especially those that were available to coin collectors.</p><p><br /></p><p>And no, I am not trying to say that the opinions of readers or other members are meaningless. I am trying to point out that commonly held beliefs are in error. Just like the coins you mention that you have that are untoned after 40 years. I&#039;d really like to see one of those. But that won&#039;t ever happen given the circumstances. But what can happen is for you take one of those coins that are untoned after these years and compare it side by side to a freshly minted coin of the same metal. Be ready for a shock though - for what you will see is that your untoned coins are indeed toned after all. It may be slight on some, but it will be there. And on most it will be plainly evident, even to you.[/QUOTE]</p><p><br /></p>
