My 1st question.....

CrossBreed · September 1, 2011 5:55AM

How do I get rid of the black crud (reverse) without ruining or damaging the coin?

Justacommeman · September 1, 2011 6:01AM

I will defer to Ricko to answer that one...............MJ

Try soaking in acetone
Don't wipe it.

some looks like old PVC and that is not good, but I could be wrong.

one thing you can try is put a toothpick in dip and touch the toothpick to the spot on the coin, then rinse, rinse and rinse again.

That isn't coming off without some kind of dip.

...that may be permanent.

I'm with the "leave it alone" folks.

A soak in acetone might be wise in case that has some PVC on it but I think most of the "black crud" is nothing and should be left alone (acetone won't change it, it will only help with the PVC if there is any).
That one dot on the rim looks to be the worst thing and I don't think it can be fixed.

Try to soak it in acetone.

When they say acetone...what they mean is PURE ACETONE, not the finger nail polish removal stuff with tons of moisturizers and other ingredients. Use in a well ventilated place. When people say rinse, they mean it! Rinse for a good couple of minutes do not let any residue to remain on the coins. Carefully AIR DRY...no need to rub it dry with towels or paper towels etc....hold it by the edge firmly and carry it around for a minute...it will dry on its own...no need to risk hairline scratches! Many people will say NOT to us q-tips due to risk of rubbing the coin and creating a hairline scratch...they are right to warn you and suggest extreme caution...but if done carefully to blot the spot and if you know what you are doing...you can get away with this....same with tooth picks....be really careful. You just want to neutralize the gunk so it causes no more damage and so it rinses right off.

MS70 is another product that might work...same rules apply, be darn careful. Good luck!

All of that being said, I think you will end up with a neutralized GRAY SPOT on the coin...luster will be impaired. That black has eaten away at your luster. When people suggest leaving it alone in this case, they have a VERY HIGH CHANCE OF BEING RIGHT! Sell it and buy a problem free example...probably what I would do.

Don't touch it.

It's a beautiful, original coin that would be ruined.

Myqqy · September 1, 2011 3:50PM

Nice photos BTW... I think i'm in the "leave it alone camp"- there could possibly be some pvc going on, but i don't think so. I don't think dipping out some very minor toning is going to be good for the coin. Learn to love the toning of the ages??

micmt · September 1, 2011 4:24PM

very nice pictures. Im sure at original size it does not look so bad. Id leave it along.

CrossBreed · September 1, 2011 4:40PM

Thank you all! I will leave the crud....alone. I don't want the luster to go away and ruin the coin.

crypto79 · September 1, 2011 10:51PM

sell it and buy one with out it

ricko · September 1, 2011 10:56PM

I agree with Crypto... if it bothers you, sell it and get one that makes you happy. I do not think acetone will remove that spot... and not sure what may be underneath it. Unless you are experienced, you pose a greater danger to the coin than the spot. Cheers, RickO

Shamika · September 2, 2011 1:03AM

I honestly think I prefer the coin WITH the spot. I'd leave it as is.

BillJones · September 2, 2011 1:15AM

Acetone can't hurt, but I don't think that it's going to come off because it's part of the coin. In other words, the silver is oxidized to its final state.

astrorat · September 2, 2011 1:25AM

Sell it and find a problem-free example. There are a lot of nice San Diego commems out there. Acetone and/or a "dip" may remove the surface crud, but I would be willing to bet you a steak dinner that there is surface damage to the coin lurking underneath. This coin is not worth your trouble, let somebody else play with it. Buy one you like instead of trying to "fix" this one.

Many brilliant men and women numismatic sorts before me taught this lesson with coins :

"If it's bothering you, it's not for you. Exchange it for one that is for you and let it go." (paraphrased but you get the idea, right ? )

My 1st question.....
