Hello guys! I will reopen the topic how to clean properly silver coins without damaging it. First of all, I know it is better to not clean them. But when you have some coins on you almost can't see the year, with a lot of dirt and corrosion on it (look at photos), you probably want them in better condition. We can say to prepare them for CONSERVATION. As you can see in the photos, my coins (silver.835) are pretty old and valuable, but in very bad condition.      I started to clean few coins especially in lemon juice. I changed the juice few times because it get dirty.    Now I put coins in the new juice and nothing happened. So, I can say, the dirt and corrosion on them is gone but the coins still have gray/black color. Now the questions are: 1. The color of the coin is patina or is some bad corrosion who get in composition of material? 2. Why this color didn't gone from coins? 3. I should leave the coins like this or I should continue with cleaning process? 4. On some coins I have black spots which looks like they are in the material. What are those? I opened a topic like this in a local website. There are participating a lot of collectors and I hope at the end we will have some good results in cleaning silver coins. Thank you in advance for you participation!     |

More coins have been irretrievably damaged by cleaning than from any other type of destruction.
While the coin you show does look nicer in the end, I simply wouldn't post anything about cleaning myself. Too many folks think they can be careful and nothing bad will happen.
Bad happens to coins still to this day over and over again. In many instances it is a dishonest way of selling cleaned coins to newer collectors who have no clue how to spot even the most abrasive cleaning regimens.
I am not suggesting you do so, but I'd rather see coins stay as they are with only the use of water jet dirt cleaning and pure acetone cleaning as options.

As already stated, you have to be careful with saying anything about cleaning coins here or anywhere. So many will only read the cleaning coins is great part and start doing STUFF on coins. So many coins have been ruined by people not knowing what they are doing. And remember yourself that acids not only remove dirt and stuff on coins, also some of the metal too is now gone.

Your cleaning has improved the appearance of the coins but they are still obviously cleaned/damaged. Having said that, I will also say that they ARE more attractive and saleable now. but they would still bring less than an uncleaned coin.
Your coins are old, but not particularly valuable.

You say you can properly clean silver coins without damaging them .Your method doesn't work very well as I can tell those coins have been harshly cleaned . As stated above this is not a very good example to be passing on to this forum's new members . Newbies in the coin collecting spectrum are very vunerable and will heed to what ever they hear on CCF . We take pride in giving ALL members the best possible advice on whatever questions they may have . CCF boasts some of the best people in the numismatic field to handle any coin or currency question or problem .

 alin per! While they're your coins and you can certainly experiment with cleaning them. What you're doing isn't conservation. "Conservation" means restoring a coin without doing ANY damage. Experimentation would rarely, if ever qualify. They do look better (less encrusted) and you should quit while your ahead. Any more attempts to make your coins clean and shiny, will do damage. For info on how to do that, just google coin cleaning. You'll find lots of ideas. All bad. Edited by Standfast

Experiment as you like but my advice is to buy a better coin to replace the one you have cleaned. I've experimented on some lost causes before. Most times the results don't satisfy me. Those coins go in the bad idea pile and I get something else that I like better. |

OMG. I am new here and I can say I can't find how to quote somebody's reply. Can somebody put a printscreen of how I can quote a message?

Yes, this is good advice. But, I bought a lot of coins from a person who had those from his grand grandfather. For me is very important the story of the coins, the locations where they were found and things like that. I newer sold coins which I bought directly from the 'source'. I don't like to buy coins from collectors which are making business with them. |

I don't want to distroy them, I only want to make them look without material deposits. |

Your coins are old, but not particularly valuable I have some which are more valuable. I am trying by posting everywhere, to find all I need to know what to do with those coins. Definitely, I will not sell them. |

I will try acetone on other bad silver coins. Do you think acetone is the best solution? I tryed before to put a coin in the lemon juice to clean simply with water. Nothing improved. Also I tryed the method with baking soda and boiled water. This one have results but not the best ones. Maybe I will wash them all, and then put in 50x50 leuchtturm holders and keep them in this condition. What do you think? |
