how do you safely remove small dark toning area from edge of gold coin?

NumbersUsacom

I'm not refering to the dark pin sized spots that can be seen on some Gold coins, but rather a small amount of dark toning on approximately 5% of the very rim/edge of the coin that appears to have occured by contact with a silver coin.

Sorry no pics.

...theres something else going on there. Gold is inert, gold coins are 10 % copper. Rubber, or high sulfur content paper, maybe..... Silver...shouldnt be any way I can see that contact with gold can cause anything...

something else going on there...like the previous poster suggested...send it to NCS

I don't think there is a safe way, but I was thinking grinder. LOL

I know we can all assume whats going on with this coin, but with no pictures, this THREAD IS WORTHLESS!


It could be a number of things on this coin and even the op couldnt really make it clear what he was talking about. Copper spots? Dip residue? Theres just too many possibles for this. NCS seems like they do a decent job, but Ive never used them or owned a coin slabbed by them.


I personally think if its a eye sotre, you should get rid of the thing. If its a rare coin, then maybe NCS is a good thing, but if its a common piece of gold, buy another. Why keep the dreck??

I think I'll agree with Stinkin's either/or recommendations ... NCS or "why keep the drek"

I realize a photo would have been most beneficial, but I don't have one to post.

Thanks for all your input and puns

Usually gold doesn't get "dark toning areas".

So, it must be "unusually toned." Leave it.

...I think it would take a north korean colonel to pry more info from the op.

I asked twice, what type of coin....

gold!


specifically... what coin is it? 999 fine ("pure") gold is one thing, an AGE is another, etc. i.e. the gold composition comes into play here.


So, specifically:

what coin is it?

I believe that there is a magic black felt pad that can cure gold coins of all there problems?

HalfStrike

It looks like all gold has other metals in it. Here is a graph of what they found in supposedly pure gold coins.

Silver, Copper, Iron, even platinum and palladium.

NumbersUsacom

Ok I speak, ( this is the first chance I've had to check the forum happenings)

The coin is 90% Gold composition, and supposedly 10% copper.

ambro51

Oh heck with the addition of that concise information the answer is obvious.

NumbersUsacom

Ok, I took your advice and got rid of the "DREK" . The coin was on approval so I sent it back. I don't like the idea of dipping an otherwise nice coin. Never sure of the results.

Thanks for helping me make the right decision.
