I've never picked up a coin with a glove on. I refuse to surrender any dexterity whatsoever when handling a collectable coin. Of course, I know how to handle coins, too - I'll be the first to slap someone I see holding a Proof in the palm of their hand.  |

I agree with SsuperDdave, I am a dealer and I know many,many dealers and none of us wear gloves. If you look at the PCGS grading videos on youtube you`ll see that they do not wear gloves when grading coins. Once you learn how to handle a coin properly, gloves can actually be a hindrance.

for verdigris use bad-thad's VERDI chem / VERDI gone.
works wonders and cant possibly do any more harm than the green rot that is happening on the last 2. not sure what it will do for the white splotching but it wouldn't hurt to try along with an acetone rinse. I wouldn't touch the top coin.

there are only two things to keep in mind when considering cleaning coins -
1. don't do it; and
2. if in any doubt, re-read rule No. 1.

A bit of disagreement. It sort of depends on the coin too. For example if a coin is worth only face value, you have little to loose by experimenting on cleaning. However, contrary to that is, although a coin may not be worth anything to one person, it could be the one needed by someone else. With those presented I see nothing wrong with an attempt to improve them with a dip in Acetone. Might not do anything but will not do any damage either. If Acetone does nothing, then the next step is to attempt to stop whatever is causing what you see on them. At least placing them in a 2x2 flip will sort of make them less vulnerable to whatever is causing them to continue. I've done some extensive attempts on cleaning such coins and in the end, basically ruined them. So many methods are posted on the internet on how to clean a coin and possibly posted by someone in an insane asylum.  Actually so many people just post stuff that they have no idea what is real and what isn't. As already stated, just don't clean coins. Isn't it odd about cleaning. Don't clean a coin. Do clean your cloths. Don't clean old furniture. Do clean your car. Constantly wash your hands. Don't clean an old Mummy from Egypt. |

This reminds me of this guy over on a Korean numismatic forum who posts results of "Cleaning Experiments" continuosly. So what he does is cleans coins in bizzare ways, and posts a X out of 5 star rating for each method. So far he has cleaned a coin using chicken breast, various types of fruits, a cucumber, soda, sesame oil, mud, his own saliva, etc. And what's even more shocking is that people call him the Scientist and praise his contribution to the numismatic community by sharing such valuable information of coin cleaning methods. One member even sent him lots of coins for free "to be used for further future experiments," funding more coin cleaning. Yep, you are right; coin collecting is still a developing hobby in Korea, and the idea of coin cleaning is still being accepted by many collectors, both young and "experienced." Whenever I say that coin cleaning is a bad idea and it should never done, I am always bombarded by doubtful comments of notorious coin-cleaners. Sad, isn't it? Edited by Matteproof

Not trying to hijack this thread or start an argument but any coin of any value should never be "pushed" into anything. A proper fitting album or coin holder will allow the coin to be set gently into it, not pushed. Just touching a coins surface with a soft cotton glove on can cause hairlines scratches. Pushing one into an album with gloves on will prevent fingerprints but will scratch a coin. Just look on youtube at PCGS`s grading and encapsulation videos and you will not see any gloves nor will you see dealers using them at any shows.

I rarely, almost never try to clean a silver coin (possibly a quick acetone dip in some circumstances) however I frequently use Verdicare on copper coins particularly around mint marks to remove verdigris while searching for varieties etc. Verdicare works great but I encourage you to take ssuperdave's advice and do some research and learn when and how to use it properly.

VerdiCare is on the way, it looks like I have many coins with verdigris that need to be taken care of. I am going to get acetone as well, as I have many coins that were improperly stored. As I progress, I will post some results or failures. This forum has been very informative, I wish I had joined a long time ago.

An expert makes the hole bigger. The non-snarky answer is, with a fingernail around the rim. |

How does an expert properly push a coin into an album or fitted holder without a glove? It is much simpler than you think. Why just place the coin in as much of the slot as you can then hit it with a small hammer. Now make sure you first place your finger on the coin so it doesn't move while hitting it with the hammer. Never use a ball pein type hammer since the rounded end could slip off your finger and hit something valuable. If your still having problems, simply take a metal file and use it on the edge of the coin making it smaller so it now fits into those slots.  If your really not sure the above is a smart thing to do, simply use a Folder of Album made for the next larger sized coins. For example place all your Nickels in a Quarter slotted Folder.  Quote:

Can't even imagine how this would work. And yes, although you say Saliva, I've used Spit on a lot of coins. Works as well as Beer. |

The first coin is a goner. When silver toning progress to black, it's too late to use a acid-thiourea dip. If you do, the coin will clean but dull and lifeless.
The second coin has heavy verdigris which cannot be removed without revealing surface damage underneath. VC will NOT remove heavy verdigris, it's not designed for that. However, it will remove the light to moderate traces on the coin. I would soak that in VC for 24 hours (bad side up). At the end of the soaking period, use a toothpick WHILE THE COIN IS STILL UNDER FLUID and see if you can get some of the heavy verdigris off. While I doubt you'll get the heavy stuff off, VC will at least arrest the corrosion process so it doesn't keep eating away copper.
GOOD LUCK and post some after pictures for us.
