Spots and haze on gold eagles

JimDepot

First one is a $10 eagle and the second is a $5.

Is this common or am I just lucky.

I pretty much stopped buying silver eagles because of the milkspots, and now I get this.

Both are 69's and they are selling for little more than melt so I would imagine that there is little that PCGS could do.

Just a little frustrated.

I hope my gold buffs do not start turning bad.

I had my Reverse Proof Gold develop a haze on the devices after about 6 months. I sent it back to PCGS along with the mik spotted ASE's. To my surprise, it came back flawless.

Since gold does not tarnish, it has to be a residue - perhaps from the mint process... acetone should remove it... or DI water. Cheers, RickO

but the 10% copper has a tendency to "leach out" .. does it not?

I feel your pain.
Mine are not graded. I have been holding them for a long time.
I pulled them out last week, I thought to submit for grading because I thought they had a chance at 70's. And to my horror.

If this was an older gold coin, I wouldn't be surprised if a few forum members claimed that it was puttied.

That is a shame. You could try sending them to NCS, not much to lose at this point. How did you strore them?

They were stored in the original mint pakage
in a dry wall safe. I have given other coins to them and
they return a grade lower.

Why is it always the U.S. Mint that has so many problems? I have never noticed problems with my Canadian Coins.

You can send them in for conservation without having them graded. It should at the least stabalize the surface (hopefully).

That is a very good idea. So simple...that's why I didn't figue it out
I will see how they turn out and see if they are worthy of grading, thanks.

PCGS did an excellent job of removing the greenish-white haze that developed on the devices of the obverse and reverse of my Reverse Proof AGE. I was very happy and it also retained it's PR70 grade.

such a strange thing to happen to coins in such quantity.
for every coin shown here there must be hundreds more that
are nearly ruined inside the slab?

outside of the slab, it seems the fix is easy! dip.

OPA... yes, copper alloyed with the gold will tone... it is known as copper spots... and very different from this hazing. The spots actually look more like rust than copper. As I have read, the copper spots are due to the alloy not being totally homogenous. Cheers, RickO

Why didn't they body bag it for "cleaning"?

According to the Coin Conservation Handbook by Charles Frank, gold will discolor in the precense of sulfur compounds. Another reason why I now keep all my coins in vacum sealed Foodsaver containers with Silica Gel to prevent interaction with atmospheric gases:

Thanks RickO for the info....

you meant gold coins which are not pure gold... but i understand
what you meant.

Gold alloyed with copper will also tone and form copper spots.

I have a proof Gold Eagle that has developed a bluish haze. The cause of that may be related to this as well.

tahoe98

are not all gold coins alloyed? me thinks so. i guess we have to house coins in a vacuum to solve the atmosphere reaction problem............or food saver bags

Some are 9999 fine or 99999 fine which is considered pure gold.
