And, if even PCGS doesn't get that simple idea, they are not in my book for grading coins. Yeah, I wasn't real excited about having them handle my coins after seeing that on their website. Their reasoning is below** but it seems to me the chance of dropping the coin would be worse if you were trying to handle the coin without touching anything but the rim. ** Quote:
Q: Why don't graders and sealers wear gloves while handling coins?
A: PCGS graders and sealers are experts in the proper care and handling of coins. While gloves offer additional protection, they reduce the tactile sensations necessary to properly manipulate coins during the grading process and could increase the chance of dropping a coin. |

Your best bet is to sell these two impaired coins for what you can get and then by more appealing replacements. These are inexpensive issues and it's easy to find them. You should be able to buy pristine examples for little more than the silver content.

Only fresh prints can be removed. Pure acetone will do it, just by soaking, without risking damage from a q-tip or anything solid touching the coin. If the print is more than a week old or so, it's not going away without wrecking the coin.
Exactly! I have to cringe at some of the suggestions here. They will completely destroy the surfaces. The best advice is to sell them and buy replacements that are unimpared. |

And at times much worse suggestions. Tomato Juice, Lemon Juice, Walmart jewlery cleaner, toothbrush and on and on and on. Usually from those that really never even tried them. Now here is one such suggestion. Instead of attempting to remove fingerprints, just add your own all over the entire coin. Then the present one wouldn't be noticed so much.  |

You can pretty well forget removing fingerprints on copper and clad. On 90% silver, Jewelustre sometimes works.

Depending on the severity of the fingerprints and the coverage area, they can sometimes be removed by dipping the coin(E-Z-Est, Jeweluster). It is difficult enough to dip an MS coin without harming it but proofs are at a whole other level. The mirrored fields are especially sensitive and even light overdipping will impair it. IMO, there is not much difference between an overdipped proof and one covered in prints and haze- neither one are desirable.

Try baking soda and a little water.make sure your hands are so clean that there dry of any oils. With your thumbs and forefingers lightly I mean lightly rub it away in one direction. It might take hours but dont get frustrated. Keep at it lightly and adding warm water drops so often. Wont be a %100 percent but will make a big difference . and keeps lustee. Otherwise the only other thing that can penetrate oil is another oil. And just a small amounton just the print lines r. Try first on another new coin until u have it down.

Try that on a proof and you won't have to worry about the print anymore, all the hairlines all over the coin will distract attention away from them.

The natural oils in clean skin are there for perfectly good reasons, to keep skin strong and supple.
The oils are loaded with sulfur compounds, (in organic chemistry, they are known as fatty acids), and will react with the pristine polished surface of a proof coin. The oils have to be removed immediately, or the reaction between skin oils and metal will happen, thus permanently staining the coin.
Use acetone immediately after accidental handling of a proof coin, or stained impairment will be he permanent result.
If permanent impairment staining has taken place nothing will remove the stain, without leaving some evidence of being cleaned.
Don't throw fingerprint stained proofs out of your collection. I just accept them on the basis as graded circulation coins, although technically, they are impaired proofs.

It might take hours but dont get frustrated. Even better would be some sort of metal polishing compound, such as brasso or perhaps a set of jewelers rouges which would be more efficient and produce a mirrorlike finish on all of the coin's surfaces. Then you could paint some nail polish or apply painters tape to the mirrored fields and apply an acid etchant to bring back the frosted devices. |

...won't have to worry about the print anymore  totally as a result of my past mistakes on proofs. It may also be worth noting that the supposedly innocuous polar/non-polar acetone purchased at places like WMT or other re-sellers distributed for fingernails leaves obvious particulate matter upon complete evaporation etc. I'll decline to leave a descriptive and supportive URL for fear of robbing this thread. |
