the general sentiment is don't clean at all. there are those who will advocate the use of acetone, in removing organic material from a coin...which is apparently acceptable for copper coins as well. I don't know that this will do anything in terms of restoring luster, but will also not do any damage that actual "cleaning" may cause. my personal feeling is that the coin should be left as is...gunk and all. unless of course in the case of copper coins, that "gunk" may be doing damage by being allowed to remain on the coin (i.e. verdigris)

Is there anything such as peroxide, alcohol, or dish soap that will improve luster Unless a coin is in MS or high AU condition, the luster is gone and not just covered by surface contaminants. Luster is one of the first things removed by wear because luster is caused by microscopic flow lines in the metal itself. The flow lines result from the coin being struck, the metal essentially spreads(via a cold flow process) between the dies when struck. |

Thanks for all the responses. The question about albums or folder...they are the whitman style books (one side of the coin seen only). Secondly, most are coins that I have found coin roll hunting. I am currently working on posting some pics but it will be at least a few more days on that (computer problems). Is there anything such as peroxide, alcohol, or dish soap that will improve luster without damage or are you saying don't clean at all? Just looking to clarify.
If you value those coins at all get them out of those folders. Those are nice for kids but in the long run, not good for the coins. Problem one is the method of putting the coins there. You usually push them in with your thumb leaving oils and acids on the coin. Also, many find that the coins just don't fit easily so they use a soft rubber type hammer. This too is known to not be helpfull to the coins appearances. Additionally to all that is that shinny stuff in the back of the slots. That is the glue left over from the manufacturing process. Also, not helpful in the preservation of the coins. However, if your coin is worn and falls out you can spit on the back of the coin and that will soften the glue and make the coin stick. Also, not good for the coin. As to improving luster on your coins. You could use a buffing wheel with jewel stone at approximately 1800 RPM. This will for sure make those coins look like proofs. Only do this if your the type that would take the mummies at the museum and put them in a bath tub and wash them.   Some things are just ment to not be cleaned. |

While everyone here is right in what they say on the subject of cleaning, in that cleaning coins will diminish their value, you have to bear some things in mind.
They are mostly talking about valuable coins that you will want to resell and make a profit. They are alao mostly talking about higher grade coins. Thay have also mostly at one time or another cleaned a coin themselves. (You know who you are!)
IF (and that is a big if) you have lower grade grimy coins that you are not planning on re-selling. That you want to keep and admire in your personal collection, and do not like looking at the grime and crud, there is absolutely nothing wrong with cleaning them up a little. Provided you take some precautions. Remember, they are your coins and you can do what you like with them. (Even take the blowtorch to them if you so desire)
A good long soak in distilled water may loosen some dirt and will not harm them. A careful clean with soap and water should also not hurt. (Be careful not to rub them with anything that may scratch, or too firmly) Be aware that any rubbing may move dirt around and therefore scratch the surface also.
I personally do not like tarnish on silver coins. It diminishes my personal enjoyment of the coin. And my personal enjoyment is why I collect coins. Therefore I remove it. I do not have valuable coins, and I do not care about the future or present value because a) I do not plan on selling them for a profit and b) individually the loss in value, because of small current value would be miniscule.
So as I said, while the general rule is "do not clean coins" you do have to consider other factors before deciding if YOU wish to clean YOUR coins.
Let the beatings begin.

The problem with that line of thinking is that you will not be the last and only owner of a coin(unless you plan on taking them to your grave)- you are merely a historical caretaker of it. The coin will exist long after you and I have turned to dust but it is your responsibility to preserve it for future generations. |

Historical caretaker? Responsibility to preserve it for future generations? Wow! And I thought I collected coins for my own enjoyment and amusement.
I can promise you nothing I have is of great historical import. Maybe if I owned some rare one off coin or something. But I don't think a few fairly common silver coins require safeguarding for future generations. If they did the governments of this world would have confiscated them all by now.
I think you may be putting a little too much importance in something that is in the end just a hobby. One we feel passionately about, but should not place too much self importance in. I certainly do not own any rare historical artifacts.

Don't clean them even if they say use xylene or acetone. I think this kills a coin.   |

I certainly do not own any rare historical artifacts. I'm glad everyone doesn't feel like that. I'm sure in the 1850s/60s that Bust Halves were some fairly common silver coins. Thankfully some people had the foresight to preserve them for future generations. What I'm trying to say is that your "fairly common silver coins" (which I don't know what they are :D) probably aren't rare right now. But, 200 years from now, they may very well be rare... especially if they've been preserved and taken care of. Don't get me wrong.. I'm not trying to climb on a soap box and preach about coin collecting here. Please, do what you want when it comes to your own things. |

I've used MS 70,a kind of soap available at coin supply sites.It will remove grime,but not tarnish.You need to use it with a q-tip and Gently clean the surface...If that's what you want to do with your coins.I have used it on some low value silver.
YMMV,Brewzz

Thanks to everyone for their input. I'm still not sure what I'm going to do with the coins in question. In fact there really were none in particular I was considering. This was just a topic that I was wondering about because some of my silver Kennedy half dollars are fairly gummed up...they were found coin roll hunting so that is to be expected. I have a select few that are for my personal enjoyment as part of my collection and another batch that I am stockpiling in case I decide later on to sell, trade, or whatever. As for now I am just going to leave them as is until it gets to the point that the sight of them bug me. Thanks again everyone. Brandon |

Completely, positively, absolutly true. Same thinking is what happens to our air, water ways, parks, everywhere when no one cares about others. Not enough people think about tomorrow. A so called normal, everyday, non valuable coin could well be worth a lot of money in the future had it not been abused today. |

A dip in acetone will help preserve your coins by removing organics like hand grease, some dirt if not too crusty; however, if you are trying to shine them up and restore luster you are better off doing nothing at all. Acetone won't do a thing to remove tarnish or toning. I also advise against acetone for uncirculated coins. In most cases doing nothing at all is the best adage. I also don't think that the newer coin albums are harmful for circulated silver coins. They contain less sulfur and glue and pushing them in with your finger is not going to damage them, but I would wear a glove for anything valuable. Welcome to the Community.
