I allways wonder My friend a retired coindealer dips all his coins before submitting to one of the top three slabbers Those coins allways come back MS64-MS67  Now I suppose this means these guys and their microcopes cannot see the difference Oh so sorry I forgot I am talking gold coins only  I pesonally hate to get a 150 year old Napoleon 100 FF with a fresh fingerprint on it Oh and the worst acid is in cola it is phosporic acid which may even attack gold alloys |

BEING NEW, I AM A JOHNNY-COME-LATELY ON THIS SUBJECT, BUT
IT IS ONE THAT IS VERY IMPORTANT. IN THE 20 YEARS SINCE
I STOPPED COLLECTING, THE THING THAT STRIKES ME THE MOST
IS THE ACCEPTANCE OF CLEANING COINS. I SAW ONE WEB SITE
THAT TALKS ABOUT AND DOES "CONSERVATION", PLUS ALL THE
VARIOUS INPUT BY VERY MANY PEOPLE ON DIFFERENT FORUMS.
COLLECTING COINS AND THEN CLEANING THEM IS TANTAMOUNT TO
TAKING A SHOWER WITH A RAINCOAT ON. YOU (I) JUST DON'T DO IT.....
JUST MY OPINION, BUT KNOW THAT MANY OF THE YOUNGER
COLLECTOR'S WOULD GO ALONG WITH IT.

On a gold coin I do not consider acetone bathing as cleaning since nobody in the world can see if this was done or not afterwards and if you cannot see it then it did not happen  Unless you prefer your coin with a fingerprint that in time will eat the copper part and never be removable again unless you use a strong acid which everybody will see was used Avoid all mechanical cleanign even your finger or cottontips unless you have a coin with verdigris which requires chemical and mechanical operations |

I never clean coins ... well, almost never. So what happens when you find coin, been under floorboards nearly 100yrs? You know it's an old three-pence even though covered with something looks like white paint. You just have to try. So without hesitation applied terps and prodded with tooth-pick and tooth-brush. Look what happened: http://users.chariot.net.au/~villai.../Page_2.htmlCheers |

I know but I am not going to insult a jeweller by telling him he is ruining his coins My wife likes her polished 100 year old sovereign just fine One in a beagel on a chain around her neck and one dangling from a armband although my jeweller uses ultrasonic with acids and then wood chips to dry and polish |

In the past 2 years I've sent about a hundred coins to Anacs. All type coins and most Unc 60 or better. I do not like toned coins so I sent a couple test coins to them that I had quickly dipped. They came back without detection. I ended up sending all my slightly toned coins after dipping them and not one came back as cleaned, and some of them are quite valuable. Obviously I concluded they do not know the difference. Heavily toned coins ( I like to call them rusty ) will show missing detail if dipped because it will take off the oxidized portion of the coin's details. These will probably be graded as cleaned. Otherwise I would never clean coins of any kind.

As you can tell by reading, there are any number of ideas and suggestions reguarding the cleaning of coins. Most of the suggestions have very valid points and tips that if followed can do you no harm. In the long run you will adopt similar tactics to either change of safeguard your collection, and these practices will be just as valid as nyone elses methods. Use good common sense and go slow. Practice, Practice, Practice! |
