I've come across to mentions of "old" cleaning versus "new" cleaning. What classifies as "old" cleaning? How can one tell? And what's the impact on grading/valuation, especially compared to "new" cleaning?
Thanks!

An old cleaning is when the coin has been cleaned a while ago, and is starting to slowly re-tone. A new cleaning is when the coin has been cleaned recently, and often harshly cleaned.
The value of a cleaned coin is what you want to pay for it. There is no formula or chart that is 100% accurate.

Old cleaning happened a long time ago. This time often allows a coin to re-tone, which can cover up the cleaning and maybe even improve eye appeal.

Old cleaning is not as evident simply because of regained toning. New cleaning appears fresher and is more distracting. In a very few instances the reason for the cleaning MAY have been more distracting than a QUICK dip. But for those who can tell a coin is cleaned, it will almost always result in a reduced valuation. A lot of coins valued at $300+ not in a TPG got cracked out from a cleaned details designation. |

A seasoned collector can usually tell an old cleaning from a new one . An old cleaning could be if the coin dose not show original skin but may start to retain some of it's originality yet lighter in color . A new cleaning might have been done harshly which will be easy to tell. There are other types of new cleaning which may be harder to tell like using acetone or if the content of coin is Silver , a quick silver dip . And then there's the simple distilled water and a drop of mild liquid soap . yes a verified cleaned coin will have less value than a coin which was never been cleaned . The moral of the story is : NEVER Clean Coins .  |

This is an old cleaning http://goccf.com/t/307552This coin was cleaned probably in the 1800's. The halo around the stars and in the crevices indicates at one point the coin was cleaned and those areas remained untouched. Therefore when the coin retoned, they are a different color. The lightness on the high points may have happened then or much later. Coins like this are pretty much considered original by most collectors as it is an old, old cleaning. Any hairlines which may be in the field are obscured by the toning. |

Word of caution, a halo around stars or lettering does NOT always indicate the coin was cleaned, especially on higher grade coins. When the coin was MS all the fields had flowlines and luster. But as the coin wears the flowlines and luster are removed. BUT the stars and lettering being higher in relief protect the field around them creating a halo effect. That protected field and the worn no luster field will frequently tone differently so even if the shine and luster fades the stars and lettering will still have a halo around them even if not cleaned. Also dirt and skin oils will then to accumulate around these raised feature in circulation. This can also cause differences in toning around the features. Then if these organic materials are rinsed away in an acetone bath, a method which everyone pretty much agrees is OK and not "cleaning", it can revel a halo around such features as well. So an original uncleaned mid to high grade coin CAN have a halo around stars and lettering. And just for the record in that thread you called the coin original and untouched. Now in this one you call it cleaned. Edited by Conder101

I tried to debunk the halo myth in this follow up poll. http://goccf.com/t/308100 I agree with Conder101. The fields will be exposed to fingers during circulation. The tight crevices between the letters and stars don't suffer the same fate. The tight crevices shield those areas from the constant rubbing and touching that occurs on the fields during circulation. Essentially cleaning the fields through constant contact. While the crevices accumulate dirt and grime creating the difference in toning or 'halos' that so many old coins exhibit. Edited by MikeF
