The coin was dipped to remove unwanted toning.

Cleaned is when you do it.
Conserved is when you pay someone to clean it.

Sadly, I'm in the cleaned side as well. Already looked like it had a previous dipping/cleaning in the first one, second pics look over dipped.

It's a common Commemorative - hopefully first set of pics are what you have - last set looks "washed out" from an over dip/cleaning!

I was hoping someone who had a coin conserved by a TPG would see this post and reply. As I said earlier, in hand, this coin looks BU and has as much luster and cartwheel as any graded MS coin currently on ebay. It's only when magnified you can see where the tarnish interrupted the surface and caused damage. I want to know if a TPG conservation service results are any different Coin Help did a YouTube video a while back where he dipped in EZ and it came back from PCGS with a grade and not marked cleaned. So... ? |

Out of curiosity, how long did you dip this for jaberwoke? What was your process?

The post-dipped coin may have as much shine and brightness as before, but there's no question that it lost some luster, probably from spending too much time in the dip. Good technique is one aspect of dipping a coin, but just as important is finding the right coin that would benefit from a dip to remove unattractive toning. Your coin had heavy, terminal toning with some underlying corrosion, and a brief dip wouldn't be enough to remove it. So by removing the toning with an extended dip, the rest of the coin got overdipped and lost luster. A TPG service probably would have said it wasn't a candidate for conservation. |

Quote:I was hoping someone who had a coin conserved by a TPG would see this post and reply. I have sent in a AU58 Morgan silver dollar to PCGS for conservation of some black terminal toning. The coin after conservation, came back AU58 with the black terminal toning removed, but the black toning had etched the surface where it was removed. All PCGS had done is dip the coin in an acid something like eZest and called it conservation. Your coin was dipped in an acid to remove the toning. Look at the stars left and right of the date, the removed black toning etched the surface of the coin. The same thing happened around the number 14 as the surface is etched from the removed toning. If a MS or AU with luster is dipped correctly, the TPG will still give the coin a straight grade. If a circulated coin below AU is dipped and sent in for grading, it has a strong chance of being graded improperly cleaned. My guess it that you sent in the coin for conversation and grading and PCGS tagged the coin details improperly cleaned because it is obvious that the coin was dipped. |

Thank you @hfjacinto. I read the posted link and found it interesting and informative. To all who wanted to know how it was conserved, no acid dip was used. No abrasive cleaning was done. It was a simple soaking bath in boiling water and baking soda on aluminum foil for 10 min or so. Yes, the markings closest to the relief edges still show the damage the tarnish did, etching into the silver but the soak method does not remove the silver as it's an electrolysis method which converts the oxide back to silver and deposits the rest onto the aluminum. It's a well known silver cleaning method used so as not to remove any silver and has no effect on the untarnished silver areas. This method does not affect the surface of the coin as far as I have determined. I proved it to myself by taking a silver bullion round that has a proof like finish and soaking it in the same bath. I saw no loss of luster or surface damage. I paid $26.80 for this coin on ebay with tax and shipping. As I said before, after the conservation, in hand, it looks a lustrous BU coin with luster and pronounced cartwheel. I suggest trying for yourself with and inexpensive tarnished coin. Grab a soup bowl. line it with foil, boil a half cup water and dissolve a Tbsp. of baking soda in it. Pour it over the coin and let is sit 5 - 10 min. You'll be surprised. Now, I don't suggest doing it to a well worn circulated coin but a nicer coin showing mint luster, as I did, a bullion coin with tarnish that has no collector value just so you can see this has no affect on the clean silver surfaces. Thank you all for your comments and guidance. |
