My First Attempt At 'Dipping' A Coin.....kennedy SMS

My understanding is that one should only dip a BU coin, those nickels were circulated. Let me explain, the BU type coin will not show the bright cleaning like a circulated one will. There are folks that say a bu coin that has been dipped will have a microscopic layer removed from the coin and this I do believe. Some like toning and some do not. I have dipped a EF/AU coin that looked like crap, and yes it ruined the value I guess but made it nice to look at the design and level of wear. I am not still sold on this dipping but the results I have seen I am pleased with. I am not worried to much about value per se, but since it was standard practice for years to 'clean' a coin, then most likely most older coins have been cleaned at one time. One thing to keep in mind is that coins can be professionally cleaned in a process that is called conservation. I wonder how they do it really but I think I have a good idea, just not the recipes used.

I wonder what it would look like had you rinsed it in acetone instead of the distiller water ? Interesting.

SInce my OLD COin Care had expired I took to the lab and developed a new coin cleaner which can effectively remove all verdigris on copper and not affect patina or cartwheel effect. It took a year but I am now satified with my results. Many rave reviews and I have been selling it only to C4 members (Colonial Coin Collectors Club) so far ... its $40 for a 2 oz. bottle. Chorinated hydrocarbons like Blue Ribbon turn a copper coin slightly purple and aceone or ketones give coins a whitish cast look as it dries out the surface. Was an industrial cleaning chemist for (15) years ... if you have questions I can answer them here ... contact me privately if you wish to purchase this item. Safe on copper alloy and hence safe on all alloys. Has no effect on carbon spots or deep cratered verdigris. Surficial PVC type green - 15 second wipe - no issues.

No name. I took a current brand and then reformulated and added a premium mix to this already formulation. The main laboratory requirement was no copper patina change, no cartwheel effects and no residue after a 1 hour drying time on the surface viewed through a 15X jewlers loop.
As with any coin cleaner it has no effect on carbon spots which are inert and depending on the depth into the coin of green patina it may need a sitting time of 15-30 minutes. Most cleaning operations with a QTip is 15 sec then wipe.
No ill reviews yet with over two dozed C4 members ging both thums up on the product.
I know ... yeah sure ... this is understandable <BG>.
I would not recommend it on MS coins because as you move the soils which are removed around there is always the liklihood of surface hairlines on the coin. But if the area of cleaning is just a green spot or two ... it may be worth the gamble>
