 Simply put...the acids etch the print into the surface of the coin. |

Can you return the item to the dealer and point out the problem coin to them? If they are a reputable dealer, they will allow you to exchange that set for another one.

Sometype of diluted silver dipping solution might lighten it up enough where it wasn't too noticeable but we all have coins like these and each is a learning experience for us to avoid on future purchases.

Once I bought in an auction, a really nice 1950 1 cent, great color, was and is a real stunner but that was 20 years ago. Today that coin still in it's original holder has a big fingerprint on the obverse. Bummer but it wasn't there when I got it home, how time changes some things.

Yes, acetone will do the trick, but it would have to be an extremely fast dip. Like, 2 - 3 seconds at most. Though, the risk is definitely not worth it. I suggest you send away for a replacement. Whatever you do, don't take the advice above to use " jeweluster" or "diluted silver dipping solution". These will drastically reduce the quality and luster of the coin, and kill any resale value.
Try talking to the dealer you bought it from, or perhaps sending it directly to the mint for a replacement, as you mentioned it is still in the original packaging.

You're right Fredd but not worth the risk unless you have some "practice" coins around. I've also noticed that the lower the coins purity = more damage, more quickly. i.e. .999 bullion can stand a longer dip than say a Mexican peso at .720....

What about a mild dish soap like Dawn or something? Rinse with distilled water and dried with a hair drier? Would that work?

 , RealMetal! Dawn prolly wouldn't hurt, wouldn't help. Pat dry, and don't rub at any point in the process. |

Welcome to the forum Realmetal
I wouldn't suggest using dish soap on a high MS coin. The idea would be to rinse with distilled water as you mentioned, and pat dry (no hairdryer) as Fredd mentioned, but on an MS coin with mirror surfaces, good luck having all the water droplets leaving without leaving milk spots. I'm sure dishsoap could be used (personally I would never use dishsoap) on lower grade coins if you were just trying to get rid of bulk dirt and grime that is loose on the surface of the coin. But there are products that are designed for coins to remove contamination that will only get worse.

I have used acetone, seems to help somewhat it would arrest future damage, I have used it on some just older common stuff, did'nt notice any ill effect. Very volitile use caution if you decide to play with it.I have seen half a soup bowl full evaporate in less than 2 hours. Make sure there is venelation and no sparks or flame.

acetone and a paint brush with stiff bristles, I see nothing wrong with cleaning a coin to stop further deterioration, and I have noticed no loss of lustre even after soaking for 8 hours ( silver coins ) rinse in water and pat with a glass cleaning cloth to dry, or paper towel.

Nope. I've seen coins worth 5 figures in PCGS holders with fingerprints on them. If there was a safe way, they would be gone.
