<p>[QUOTE="tequilaDave, post: 2425918, member: 21609"]Haze on coins is a product of the environment in which they were stored in (moisture, temp, etc.). You can potentially "dip" the clad and/or silver coins but unless you change their environment, the haze will return, not to mention the fact that post dipped coins have less "luster". As for the copper coins, there's not much I know of that will clean off the haze and not alter the color and/or mirrored finish. Blue Ribbon was a product that, if applied extremely gently (and I mean EXTREMELY gently as mirrored surfaces will show even the smallest hairline scratches that are easily made when wiping a coin) may possibly help. Unfortunately, Blue Ribbon cannot be sold "legally" in the US but yet can be found at extremely high prices on Ebay. Another option is acetone or isopropanol or something similar for your copper coins that will not remove any of the metal surface but can in some cases remove some or most of the haze. Not a perfect solution by any means but at least it won't alter the coin's metal (something that you cannot say about EZ-dip or any of their brethren).</p><p>In the future, be sure to store your coins near some form of desiccants like silica or even boxes of baking soda to limit the coins exposure to moisture, especially if you live in an area prone to high humidity. Temperature changes can also have a negative effect on coins albeit much less detrimental if you live in a dry area.[/QUOTE]</p><p><br /></p>
