Purchased for what I believe a fair price (under $150). Uncirculated details, very nice luster and cartwheel both sides. But... See the reverse. This is for my meager 20th Century type set. I try and improve the coins as I have the money to do so. I "DO" like coins as close to mint as possible and to have a look as close to a new coin as possible. I've been around long enough to know you shouldn't clean most coins but the grading companies offer conservation services. Opinions please on if this is a candidate for conservation, especially if you've sent a coin for this service and to which grading company. Any help appreciated as I'm thinking of a hot bath with baking soda and aluminium to rid the reverse of this ugly stain of tarnish.   Edited by jaberwoke

Since you've labeled it "Uncirculated details", the word "details" means to me that it's already been cleaned or otherwise "adjusted".
If that's the case then a quick "dip" won't make a difference.
But if that's not what you mean I'd leave it as is or at most give it an acetone dip.

I have only sent one coin in for conservation and it was with NGC. I was happy with the results and it did straight grade. That being said, the issues I was having were different and not on silver.
Stay away from baking soda and aluminum! You will kill any remaining luster and original skin on the coin, and will usually quickly turn a golden tone. It will not remain white.
Others may recommend a quick dip. I've never dipped, never will, so I can't speak for it.

The word details is often used to describe a coin with nice details. But to most collectors, "Details" is a term for coins that are improperly cleaned or damaged.
If the coin was listed as a a "details" coin, then you might have paid too much. I don't think it looks cleaned, so not exactly sure why you used the word "details". Unattractive toning doesn't usually result in a details grade. But it does lower the value.
That toning is pretty dark. I doubt your mixture, or even a coin dip is going to improve it much. A profession conservation by one of the TPGs might work. But you never know until they try it.

I don't think it's going to come off, as least without showing more damage.

Soak the coin in Acetone you may get lucky.

Being new to this forum, I may have used the wrong word to describe the condition.
I have the coin in hand. It appears to have been lightly circulated from the nicks and scratches it has but it doesn't show the usual wear from circulating for any great length of time, Thus my use of the term "uncirculated details".
Leg, knee, thigh are not worn flat. The eagles leg, breast and leading wing edge are not worn. Full head, bright luster and cartwheel on both sides.
I have done a baking soda bath on a couple of coins with very pleasing results and I wonder if this simple clean is one of the methods the grading companies use or if they have some secret method not shared with this community. The near uncirculated coins I have experimented with came out beautifully.

Do not soak the coin in baking soda. Use Acetone first if it does not work your options are to dip in acid like eZest or send to TPG for conservation or leave it alone. The acid dip or conservation is most likely going to turn the coin bleach white and it will look like a dipped coin. I would leave it alone. |

I think your coin has already been dipped a few times too many.
Any additional dips will kill any remaining lustre.

First thing that came to mind was,is it genuine? Second,if you need to so called clean it use only 100% pure acetone. John1  |

Looks to me like that area on reverse is set into the coin unlike toning would just be on the surface of the coin . Either send it in for conservation or leave it be .  |

It looks like a patch of sulfur tarnish, maybe from contact with the corner of a piece of paper over many years. An oxidant like peroxide would probably remove it, but it would damage the coin's patina.
I use silver cream all the time to clean tarnish off sterling silverware, but the objective is shininess not original surface preservation.

I've used NCS from NGC before and they are really good. I would let them try to remove the spot or leave it be, don't try to remove it yourself.

Leave it as is  I would feel better taking the money spend trying to conserve and use it to buy a better example. If it were something with sentimental value (to which I can relate) then I would not want to risk further damage. |
