How to remove a carbon spot

@littlecoin, I know there is advice for you about the hardened glue on your coins on old threads. Try the search function using "glue on coins" or something similar. If these are not valuable coins, experiment with one using Goo Gone, and rinsing afterwards with acetone. I might get slapped for saying that ; the old threads may have much better advice. Or start a thread about it.

@littlecoin, I forgot to mention that using warm water and a Q-tip for masking tape residue would be futile (it won't work well) and harmful (leaving a multitude of hairline scratches). I'm glad you stopped!

NGC has a conservation department that will professionally clean coin, they can do it but of course no one else can? Some coins are just best left as they are. It all depends on the person investment in the coins, of course.

 

@Stevearino

ty so much! i dont know if they're valuable, maybe some are...but those that are goopy I need to clean to be able to see...i'm a newbie to this (been amassing thousands of coins over the years but never looked at them ..started a few months ago) ty again!

i got the acetone (i clean my painting brushes with it sometimes)...going to read that page thank you!!

 

Yes, but you didn't mention that part, and there are a lot of readers who haven't learned that distinction yet. Try to always be aware that, even though you're talking to the one specific person who posted the thread, there are another hundred listening over your shoulder. Many of them have not yet learned not to clean coins, and will think what you're offering is generalized advice for "normal" coin conservation.

 

Thanks for the advice, as I am new to this site.

 

So I am reading this thread and I myself was wondering about white vinegar? Or maybe using a bit of baking soda with it for a small volcano!!!

 

I'd use baking soda dissolved in boiling water in a bowl with some tinfoil lining the bottom of the bowl then let the coin soak in that for a few minutes. I'd then rinse the coin in fresh water followed by distilled water and then and put it in an envelope to retone for a few weeks. Sometimes dark spots like that won't remove and will just lighten up a bit even if you spot apply dip and try everything else. But still makes that coin a wonderful practice coin.

Imo too many people are afraid of doing absolutely anything to a coin but when you do it right it's not really like you've done anything at all. Practice makes perfect as they say.

 

I'm reminded of an old post where someone bought some silver dollars at a gun show and when they went back to pick them up, the seller had cleaned them really good with an eraser to help the buyer out.
