Red spots on .9999 pure gold coins?

All I know for sure is that gold will not rust, even if it's buried for for 5,000 years.

One of those gold plated "tribute" copy cat coins is listed as being layered in 3 mg of pure 24k gold, This means if the coin is a one ounce copper coin, and has 3 mg of gold layered on it, it is 31,103 mg, (hypothetically) 3 mg of Gold 31100 mg of copper that is would make the coin .999 copper, yet the gold would cover the entire surface of the coin, giving it a gold appearance, so red spots are not to be considered as even minimally effecting the stated purity of a gold coin.

Collectors are not always so worried about the actual composition of a coin as they are about eye appeal, so a coin with red spots would have more collector issues than a coin without, even though both are refined to the same standards.

Is it possible to achieve 100% metal purity? Perhaps, but it would probably make the production costs much more.

This off the top of my head, so tell me I am wrong and why.

 

You do realize that even if you find a perfect coin red spots (caused by impurities) can manifest years after the coin is minted? That is likely what happened with MS70s.

 

i heard in coins mixed with gold and copper, they may have red spots. but never heard of a 9999 gold coin with red spots

 

I have a buffalo that I purchased from the mint, stored it in the original mint packaging and noticed a red spot "growing" last year. I wrote to the customer care center at the mint last week and low and behold, they set up a call with the quality control department. I sent them some very good, high density pictures and got a reply just today: (I deleted the guys name and email address in fairness to him)

Mr. Scott,
After conferring with a few of my colleagues, we believe that’s it’s a drop of oil. Obviously we’ve seen spots on coins for several different reasons (some of them still unknown), but in this particular case given the information and pictures you have provided, our best guess is a drop of residual oil may have been left behind from when the press operator lubricates the blanks.

The size, color, and “growth” of the spot have yet to be reported on other 2007 Gold Buffaloes so at this point we’re assuming this is an isolated incident. Regardless, we very much appreciate your candor in bringing this issue to our attention and apologize for any inconvenience this may have caused you. We’ll be sure to keep our eye out for this issue on other Gold Buffaloes, both those that have already been produced and those that have yet to be minted.

Thank you once again for being a valued customer and we hope you continue to enjoy our products. It was a pleasure speaking with you.

Take care,

My issue is this: MY red spot seems to originate from a single pinpoint and appears to "grow" from that point. Im not a metallurgist, but my spot isn't a drop of oil; its a defect in the gold round ... probably a foreign metal of some sort. While I am an avid reader of this forum, this is my first post ... so if you are interested in seeing the detailed pictures, let me know.

Oh yeah, one more thing. I sent it to PCGS just to see the impact of the red spot and it came back PR67DCAM.

Well it happens.

Here is a 999 UHR I got from mint. I find the color beautiful. Many won't buy it, some will. Doesn't matter as it's not for sale!

Spot is in the ray below the eagles mid-chest. If I had uploaded a larger picture, you'd see it's a beautiful scarlett color. It may not rate an MS 70 but it's unique. This copper spot hasn't changed in size since the day I received it.

 

has anyone had their red spot turn blue after a period of time?

 

Don't tell me you have Spock. :devil:

 

As in previous threads on this, red spot problem on .9999 gold, I have stated that my 2006 AGB was perfect when the US Mint sent it to me. It never left the gov airtite and was kept in a dark, moisture-reduced, temp., controlled safe. When I went to put it in a safe deposit box in a bank, I then noted the bright red dot somewhere in a crevice on the obverse. I was dismayed. Then, after contributing to the thread on the RED GOLD SPOTS, first I was kind of relieved to find out that I was not the only one that this was happening to, and a that a .9999 gold coin can and may spot as seen by too many of us.

At that time I concurred with Doug, and still do today. At least on this topic. And most others.

 

Hey Bruce.......any Donald Fagan running about in the head lately?

 

Always, my friend.

 

LOL......me too.

 

yes my stuff is special not the left over lot dished out to others

 

hmm well i never agreed with grandpa eventually he started to agree with me. he has had a big holiday now so his spirits must be up. i dare say we might even get another edition of the 3 stooges

But gold tones and i cant wait for the hypocrisy to end so either all toned coins get a premium or all get a discount

come here grandpa and tell us on how to remove the gold toning

 

Yes unf. bullion stackers see red spot as some kind mark of shame and i have seen countless bullions' with red spots going for below spot price (in fact i have bought a few of them AGE and Swiss gold coins)

 

High school chemistry was a looooooooooooong time ago, but I still seem to remember that the only acid which will affect gold is agua regia, a combination of nitric acid and hydrochloric acid; so while a brief soak in acetic acid (aka vinegar) might get rid of "an oily substance" it sure couldn't damage the coin.

 

Yes, I have 2 1oz gold bars. one that was out of its packaging for Who knows how long, it has bite marks in it scratches.. etc.. call it bar 1.. and another. bar 2, that was still in its packaging when I purchased it.. I do not know the mint date of either.
I understand water memory and how gold is extremely special with regards to energy vibrations and its other abilities.. so I put bottom my bars in my water filter basin. Now, a couple months later, I cleaned my basin.. Bar 1 was unchanged, and beautiful.. bar 2 had red spots forming.. 3 to be exact. to on the top ( 1 tiny and one not so tiny) and a third spot on an end. interestingly, there are all very localized on the bottom 1/4 of the bar.. the largest spot, on the end, is read on the perimeter and shiny blue/green on the inside of the spot.. Very Strange.. Maybe gold itself has a visible change due to the vibrational change everything is going through as we move through this section of the galaxy.

 

I have not read this whole thread, but wonder if the spot could be surface contamination by iron/steel. There's a fairly common issue with US made cars that are shipped by train. Called "rail dust", it happens if the car is not washed well and soon after delivery. Tiny particles of iron from the rails coat the vehicles during the rail travel and turn into red rust powder in the nooks and crannies of the car.

Now, I am not suggesting that the Mint sends out gold bullion in open rail cars, but... Maybe something similar?

Sent my UHF to NGC for grading. It came back as a MS69 and recommendation to forward to NCS to remove the spot. I'm sorry but I still think it's unique and beautiful. It is also as it came from the mint and not altered. If I have to have someone change the surface of my coin to give it a MS70 rating, I'm sorry. I'm not trying to satisfy third party grading companies, I'm trying to collect a coin that represents what came from the mint. I know that ANACS, at one time, graded coins to reflect how it resembled what came from the mint, if it came out their doors with a silver spot, so be it. Now we collectors, that buy in slabs, are hung up on beauty only. Worse than that, these companies require a multitude of graders to see the coin the same way; hope none wake up having a bad day (it just takes one). Finally, the graders are taught to look at certain areas most closely. I've seen some pretty poor looking coins with high marks, only because the hair curl under the ear was well defined. I'll stick with my MS69 and it's red spot. Find it very chemically exciting to see the mar in pure gold.

 

The only reports I read on forums about NCS removing red spots is that they do it by heating with a flame on Chinese Panda gold coins. One report was that Chinese chemists had determined they were sports of silver and sulfur (??) compounds, I think it would indicate refining problems with the Chinese pandas rather than a normal situation with all gold coins.
