The key to properly cleaning coins is to know which coins you can clean and which ones you can't.

I agree and would like to add you have to know which you have to clean and which you have to leave alone I only preserve coins my cleaning days are over Like this week I got a 175 year old gold 40 FF Charles X Under the closest inspection the coin did not look cleaned ( 10X led magnification ) but it must have been because there was green plasticizer rot from pvc in the kings ear and only the ear which is one of the lowest points on the coin A dip would have removed that a wiping cleaning not I had to soak it in acetone for four days before the green rot was completely removed It still looks uncleaned and sits in a mylar holder in the bank now |

Sorry but my thoughts, and the belief of any dealer worth his salt AND the majority of experienced collectors, is always going to be Don't Clean Coins. Don't clean the ones you think you can't. And don't clean the ones you think you can...it's easily detected and will hurt the value and earn the coin the title of "cleaned" forever. Nick |

i would never use chemicals to clean a coin becouse of the possibility of disaster. but with my roman coins saoking it ib mineral watter, then taking it out and scrubbing it with a copper brush or stiff brush will clean it nicely without damaging it. it does take patience but it works!

I agree and on an inexpensive coin like that, you aren't oing to send it to NCS. ;) Having said that, I don't clean coins if it takes more than water and a soggy toothpick and I haven't done that but once or twice to get a particular piece of gunk off. I will either shy away from buying a coin that needs to be conserved in the first place or sell it off as it is if I happen to end up with one. I don't trust myself to mess with it, don't trust the people who might mess with it for me for free, and none of the coins would be worth paying a pro to do it. |

personnaly I think its fun getting cons that are uncleaned, dirty and unadenified. usually threr cheap and you never know what youll find. plus you dont have to blast it with chemicals to clean just scrubb it and it will be clean and not damaged.

but id only do thison coins ware you cant read anything, like my roman coins have been in the ground for thousands of years and have thousands of years of gunk on them unlike that nickel. so if you read and seee most of it dont clean it.

In my opinion usign a copper brush is worse then using any kind of chemical because first water is a chemical H2O and second apart from a chamel hair brush I can see any kind of brushing easily |

Ancients are a different story (and one I know little about to tell the truth). When you have an encrusted, dug up, bit of something or other that might be a coin, I would imagine what what is 'acceptable' is different. |

To clean or not to clean and if so how is perhaps one of the most asked about question. I follow the simple rule of "NEVER" .
Having said that, a few collector mates have tried digital ultrasonic gizzmos and I am getting very mixed feedbacks about them...ranging from "Brillant" to 'Mediocre". I am wondering whether any member here have tried them.

I have tried them in the lab , there are many machines on sale that only vibrate A real ultrasonic is expensive They are mostly used by jewellers and then together with specialised mixtures of acids detergents and reducing agents The only advantage over a conventional dip is that they are fast and reach inside intricate woven jewelleray bracelets The reason the results are mixed is because of the quality of the coin before cleaning A real uncirculated (non copper coin ) will mostly come out a lot better it you haven't let it bang around the bottom of the machine But in my opinion this type of cleaning will be visible under magnification on many coins |

Electroplating is putting gold or another material on iron or copper or silver by using electricity , two electrodes and a liquid bath You must mean electrolyses were you try to get product off a coin I know somebody who uses it on coins found in the ground with a lot of encrustration on it He uses a mixture of baking soda and salt in water and gets all the dirt of in a few hours I personnaly would not recommend this on anything then low value coins straight out of the ground |
