I have heard from several people on this forum that if you put a coin in a Manila envelope for several weeks, it will tone. My questions are: if you put it outside, do you leave it to be rained on? Is it the paper or the adhesive that causes the toning? Thank you.  (P.S: I'm only going to try and tone a worthless clad coin. Not going to damage anything of value.) |

You can also use Taco Bell napkins. John1  |

Brown kraft paper, not manila, and it will take much longer than a few weeks, especially with clad coins. The kraft process uses sodium hydroxide and sodium sulfide to convert wood into wood pulp, the residual sulfur in the paper is what causes toning.

Clad will be much more challenging to tone. John's suggestion of Taco Bell napkins has been done before and it has produced some very colorful toning. I am currently working on one myself.. I have a silver eagle loosely wrapped in a napkin and sitting on a back porch window seal.
It is a slow process that will likely take months before you see any results.

Bad mojo that toning thing. I stay away from any toned coin unless it is certified. I have seen some that were baked, frozen, left outside and abused its pretty obvious. Heck throw MS Red copper cents in an old pickle jar and you get some toning in a couple years. I like toned coins but too many people got ideas about being tonemiesters and theirs too many "Questionable" as it is.
I have one certified toned coin a 1966 SMS MS-67 and it is beautiful I gotta admit, they do bedazzle a fella.

Toning. Artificial, natural, man made, a passionate subject with strong opinions. You ask one question, expect many different answers and opinions. Is someone going to tell me this guy isn't making these? http://www.jhonecash.com/coins/tonedmorgans.aspHe's making money and the TPG'ers are making money. |

I think they look cool, but I can't see it being anything but a fad. At the end of the day, the coin that is still closest to how it left the mint should in theory be worth the most money. Toning in my opinion is no different than counter stamping coins or dipping them in acid. It ruins the original luster and look, despite some of them looking very pretty.
IMO :)

Yes, because many of those have a provenance predating the current owner, and many were never actually the property of that dealer. That page is a reference source; only 7 coins of the 75 pictured are for sale. |
