<p>[QUOTE=&quot;GDJMSP, post: 2160938, member: 112&quot;]Haze, or what most commonly refer to as haze anyway, is the beginning stages of toning. As such, acetone will not remove haze or affect it in any way. Neither will xylene, or anything else, short of coin dip. Coin dip will remove haze, and any other toning. But unless you have a good deal of experience using coin dip, you would be best advised to not use it for it is all too easy to permanently damage a coin with coin dip.</p><p><br /></p><p>That said, there are contaminants that can get on coins and cause the coin to have a hazy looking appearance. PVC residue for example, in its early stages, can have a hazy looking appearance because in its early stages it is clear. Some oils can also have a hazy look to them, as do a few commercial coin products. The problem is you can seldom tell with any degree of certainty what exactly, if anything, is on a coin. And because of that you seldom know what exactly what to use to try and safely remove it because different contaminants require different things to remove them.</p><p><br /></p><p>But there is a simple process to follow to try and remove the contaminant, if there is one, on the coin. Rinsing and or soaking in distilled water is the first step. If that doesn&#039;t work, then you try acetone. And if that doesn&#039;t work, then you try xylene. And if that doesn&#039;t work, then a coin dip is the only thing left. But as stated before if you do not have experience with it you are best advised to not try dipping a coin.</p><p><br /></p><p>Coin Care, the product that was mentioned, although it has been used by many and is often touted as a great product, instantly turns any coin into a problem coin. As Jim said a couple of times already, Coin Care contains oils and when used it leaves oils on the surface of the coin. On copper coins it even creates false luster, less so on silver or gold, but the oil is still there. And because of that, by definition, the coin is a problem coin.</p><p><br /></p><p>Part of the reason that Coin Care is touted as being a good product is because unless you are very experienced Coin Care is hard to detect. And at times it has even fooled the TPGs and coins with Coin Care on them have been slabbed. Coin Care is one of the reasons that the TPGs began using the &quot;coin sniffer&quot;, because it was getting by some of their graders. But the &quot;sniffer&quot; is only used on some coins, only those coins submitted under the Secure Plus grading tier are run through the &quot;sniffer&quot;. All other coins are not.</p><p><br /></p><p>So you do not, repeat <u>do not</u>, want to use Coin Care !</p><p><br /></p><p><br /></p><p>Barber dime 94s - what I would suggest that you do is post some pictures of the coins you are talking about. Then we may be able to offer some advice on what you should do, or not.[/QUOTE]</p><p><br /></p>
