Quote:It is speculated (Wayne Miller) that there were at least two and maybe more conditions which made it difficult for Peace dollars to develop attractive toning, notably, a planchet rinse pre-strike and limited exposure to a favorable environment (sulfur) due to not spending much time bagged up before release. (Compare pre-21 Morgans that sat bagged for 20-40 years or more after being struck before ever seeing the light of day again.) I believe there to be at least four factors involved with respect to why Peace dollars didn't tone like Morgans. 1- Planchet rinsing (there is some evidence that the acid bath into which planchets were plunged after annealing to remove discoloring oxidation was more highly concentrated for Peace dollars). 2- Length of time stored in bags 3- Location of stored bags/harsh conditions such as humidity 4- The change in the composition of the mint bags themselves ( I know from extant documents that A Piatt Andrew ordered changes to bag materials in early 1910 to reduce cost. (The bags for all coins were made in the sewing room at the various mints.) George Roberts continued Andrew's cost cutting, so it is possible that changes in materials reduced the opportunity for toning of silver coins after the first part of the 20th century). Quote: Artificial toning that very strongly resembles natural toning can allegedly be done by "gassing" older TPG slabs. The result is virtually indistinguishable from natural toning. Actually, the gassing of old slabs leads to rather horrible toning which all shares the same "look" and is easily distinguished from natural. Note the complete lack of elevation chromatics, the wrong color progression, and the abrupt color transitions.  Edited by hadleydog

I still see a lot of toned silver going for a lot more than I think it should. It looks pretty, but it's still damaged in my opinion. You can only have the original luster once. To me it's like a fully restored classic car. Looks great, but isn't original anymore. Toning does not impair mint luster, that thin layer of silver oxide that forms on every single silver coin struck actually provides a layer of protection for what should be considered original surfaces (unless the coin was dipped prior to toning). That original luster is not impaired until the toning reaches a terminal point, or the coin is dipped. Edited by hadleydog

Below is a gassed Peace dollar with a photo after gas and before gas. The gased Peace dollars were not close to natural toning. The gased coin sold on ebay. The seller that was doing the gased coins is apparently no longer selling on ebay.  |

Paralyse, the toning gas dudes are getting better and you are correct as the in holder toning is getting virtually indistinguishable from natural toning. Latest example of gas in holder below. The before gas coin sold on ebay 10/16/18. The after gas in now on sale. All coins in the rattler holders from seller have been gassed. Check out the coin from seller: 183539113899  |

Both examples posted above scream AT, not even close, and actually offer negative eye appeal. Would that piece have fooled you Slider? |

Is this an example of gas toning?  |

From the image provided, the color progression appears both correct and subtle, and it has that 'crackled' appearance that is not evident in the AT'd example posted above. |

The "after" photo coin is AT but it would fool many, many bidders who don't have your expertise on the subject (and you do have a very large amount of expertise!!) They are the ones who will be easily victimized by these sorts of shenanigans and it is they who make up a large portion of our hobby.
Also note that the label has discolored quite a bit along with the coin's sudden outbreak of toning. 100 years of toning in a month is quite impressive!

Would that piece have fooled you Slider? I buy a lot of toned coins online and there are a lot of sellers that do have a clue of how to photograph a toned coin. On the 84 O Morgan one would question is it a bad photo, slack TPG grading or a gassed coin? The Peace dollar I posted looks gassed. The TPG grading has not helped the AT issue as they have slabbed a number of coins that I would consider AT. My point is the the gas dudes are getting better with different colors and toning patterns. I am concerned over the improvement of gassed coins in holders. |

Agreed on both counts and yes, they would fool many.....especially since they are already TPG authenticated. I know from ats that PCGS is aware of the issue. It will be interesting to see how they resolve it. |

A strong luster underneath the black toning might give me pause to reconsider, but my first impression was also terminal toning. I once owned what appeared to be a black, highly lustrous Morgan with a cool textile streak running across her cheek (purchased from Andy Kimmel). Under a loupe however, the black was composed of multiple colors. I didn't realize at the time just how rare it was, and haven't seen another like it since. Edited by hadleydog

I saved this dirty lady from the culls tray @ the LCS awhile back for $10. Never seen reverse toning quite that dark.   Member ANA - EAC - TNA - SSDC - CCT #890 "Most of the things worth doing in the world had been declared impossible before they were done." -- Louis D. Brandeis |

With nothing to lose, I dipped it after buying it using the 50/50/3 method: 1/2 dip, 1/2 distilled water, 3 seconds, then rinse with acetone and distilled water. It's actually cleared up a bit more in the last year or so while sitting in an album. There's a bit of luster left.

I really prefer originality. No toning for me.
