Hello all,
Yesterday I came across a beautiful 1986 American Eagle One Dollar Silver Proof (in Korea of all places). There is some tarnishing at the bottom of the obverse side of the coin. The plastic round case it is in squeaks at the bottom when pushed, so I think someone has tried to open it at some point. There is no tarnishing on the reverse.
My question, is there anyway to save her from further tarnishing? She is so pretty, I got the coin the same day as the 30th Anniversary AE Silver Proof set, and I'd like the coin to stay pretty for as long as possible.

I don't think you can stop the toning process but you can slow it down. Put it in a new Air-Tite capsule, and or put it in a plastic zip type bag,freezer kind and remove as much air as possible. Use a straw to suck out the air and zip it closed. Just some ideas,good luck to you. John1  |

You can't do anything to remove the toning that has occurred without damage to the coins surface.
As suggested, get it into an air tight container.

Some collectors like tarnish (a.k.a. "toning")...but...at least get it out of that squeaky capsule and into a new home (capsule)

Experts can acid dip toning and haze off proofs but there is little margin for error. I wouldn't try it and would simply store it in climate controlled conditions from here on out. The plastic capsules usually can be opened with little difficulty so don't worry about squeaking, it's likely fine.

I would say if the capsule is squeaking it is not tight and probably the reason for the tarnish. I have seen very few ASE's in capsules that squeak...probably none. Most are a PIA to open. No big expense to change the capsule and proceed from there. It might stop the progression of the tarnish..it might not. But the possibility of stopping it is worth the minimal effort and cost needed. |

Thank you all for the help. I am going to the local shop here in Seoul and will get a new case for it.

The fact that the capsule has a squeak means that it isn't closed properly. Coins often come from the mint this way. The mint capsules are so airtight that you often have to really work them down to the point where the coin doesn't rattle. It is the fact that they are airtight that makes them difficult to close fully. You might get a can of "air", open the capsule, give the coin a good shot and close it up again. Look for a product that is only nitrogen or anything that does not contain oxygen. Another trick is to get a small amount of dry ice (most full service grocery stores have it) and put it in a small deep bowl. CO2 is heavier than air so the bowl will fill with the gas, displacing both nitrogen and oxygen. Open the capsule, lower it into the bowl slowly and close the capsule while it is in the CO2 gas. Oxygen is the biggest attacker of coins that are properly stored so anything you can do to get it away from the coin is a plus.
