help on imperfection on silver proof coin

hi anybody can tell me what kind of imperfection on this coin? burn marks/toning???? on the outer rim.

thanks

 

Could be discoloration from vapor of some sort. Sometimes even the packaging / box in which some coins come in exude vapor from some substance like the glue used.

That is just normal tone....It will likely continue to expand.

 

Expand and possibly make more valuable if a beautiful NATURAL tone develops. Don't try to clean it whatever you do. lol

 

Thanks...it is 2006 red back spider, I returned back to seller since it is not mint condition.
I will add one more imperfection coin on S1 proof coin, imperfections on outer white ring/rim on queen side

 

It is not an imperfection, just to clarify and is perfectly normal for Silver to tone. Unless the coin is Physically damaged through a strike, scratch etc... then I would have an issue.

Also not sure why but the recent S2 Lunar Dragons toned really quickly the ones that I had, none of my other coins in that storage even had a hint of toning, so something changed with that run of coins?

 

But in this case, the toning will heavily reduce market price of this coin, right?

 

A. Tone - can become a thing of beauty adding significant premium basically become pleasing to the eye. As the toning develops, you have 50% chance that it could add value. However if you try to wash or clean it now you have lost big premium.

B. Tone - become butt ugly, you can always try to clean it in some future date, when you are sure it is not becoming a example of above.

What could possibly turn pure silver that colour? It looks like heat discolouration, but that can't be true.

 

I am aware of that toning affecting market value of the coin. But this is proof coin with mirror finishing, I reckon it won't be pretty with such toning/discoloration condition IF eventually expanding to those mirror-finishing area, and will heavily reduce market value of this coin.

 

how's about this S1 coin 2oz proof .....is it toning? all lunar S1 silver proof have design of small white radius of outer diameter which is not mirror-finishing on queen side.
Anyone know what is it?
any way to clean those imperfection/toning? or not advisable to do anything about it.
any feedback is highly appreciated.

 

Yes as it stands it has lost value, as for cleaning.... I doubt you can get it cleaned without leaving signs of cleaning devaluing it even more.
Not even sure taking it to professional and paying big dollars can do it "invisibly" but maybe they can.

I'd say your best hope is that it turns good

 

I think nang0204 makes a good point about the distinction of the look of toning on a bullion finish coin vs a proof coin. I have never seen beautiful toning on a proof coin though I've seen beautiful toning on bullion finish coins plenty of times. Even one of the folks who is an expert at artificial toning (AT) techniques tells me that the reason he doesn't AT proof or proof-like coins is that they don't look good toned. Here's a couple of examples of this individuals extraordinary AT on a bullion round:

and

So maybe there is a very valid reason to return a proof silver coin that already has smears of brown on it.

If you let toning bother you as a collector of silver coins then you will drive yourself nuts fighting mother nature...and she will win in the end anyway. I would not worry about the tone in either case but if I were one to worry I would be more concerned about the redback because your potential pool of customers might be smaller for a toned example.

Here is a toned proof coin in my collection that I feel looks very nice.

 

Hey op did you buy from a local dealer? Maybe you can return it for a different sample?

 

easy to remove

 

Wow mtforpar, that looks good.
I guess it is like everybody want pretty face/body, flawless....but look at supermodel Cindy Crawford black mole on her cheek...or nobody like to be bald(loose hair) but some men looks good with clean shave head.
Or some scar which looks macho.
Not many people appreciate that flawless so potential buyers get smaller.
Pretty is very subjective and different from eye to eye

 

I see that kind of toning all the time, usually because of cracked capsule.
