My herd of Buffalos - gold that is

Made a trip to the SDB so I could image my Buffalos.
I only see them once a year when I add the new member to the herd.
Same camera setup for each coin.
What a difference in color and luster between the years. Some are developing some nice toning:

Surely this subject has been discussed at length before, but can anyone point me to an old thread regarding pcgs slabs and how/why they tone gold? Specifically it seems that the slabs from 2006 through 2009 seem to be the the worst offenders. The number of *heavily* toned 2006w $5 burnished gold eagles in PCGS slabs at the FUN show was frightening (I saw at least six!). I've never seen toned burnished gold eagles in any other holder so clearly it's a chemistry issue with pcgs slabs. I've been saving pictures of examples as I come across them and plan on cracking out an example soon to see if acetone will clean it. Gold shouldn't develop wild toning in just a few years and one has to wonder whether or not future collectors are going to consider the coins as toned versus 'environmentally damaged'. Surely our beloved host has addressed this issue before so if someone could point me to that thread I would greatly appreciate it. Thanks...
Now hopefully the 2013 doesn't cost $3,000.

Turn your PMs on... (I don't want to derail this thread as I was planning on starting one on this subject at some point in the future.)
<< <i>Somehow, the designs for the gold buffalo, and silver and gold eagles have too much of a "been there, done that" feel to them. The Statue of Liberty design of platinum is well done however. >>
I'm actually VERY thankful for the age, ase, and the buff as IMO the mint is giving us modern coins with their absolute best designs ever
We need to start a petition for a high relief 100 year anniversary buffalo
I updated my profile to accept PM's

What equipment did you use to take them?
Love the Buffs. I to have noticed the variability between years.
<< <i>nice herd! My friends herd of PCGS buffs started developing nasty looking toning spots, he had to sell at a big loss. The NGC ones didn't tone at all. >>
He should have sent them in for spot review.

This corroborates what I've seen and heard from different people across different forums. Start looking at burnished gold eagles and you'll see a number of coins with toning. Even eBay sellers now state "no haze" and/or "no tone" when selling pcgs burnished eagles on eBay. Buffs, spouse gold, and particularly burnished gold eagles seem to "tone" very quickly in pcgs slabs
We'll use our hands and hearts and if we must we'll use our heads.
Agreed that it may be an impurity, but I kind of like the transitions of color from light to dark.
<< <i>These red spots are driving me crazy. My Grant FSMS70 already had formed a small red spot. Figures it was the only one that graded 70.All my 69s are still ok so far. What will PCGS do about it in spot review? >>
Just so folks aren't confused by my previous statement I was referring toning specifically, and not the copper strawberries that develop on 22kt gold and sometimes even on 24k gold. The buffalo above has mild toning, but I've seen other pure gold coins with heavier toning. This first spouse coin is much darker than it should be:
Tarnish stains on .999 or .9999 Gold coins, is caused by the presence of Ag (Silver) and S. (Sulphur) on the coin or in the atmosphere.

My friend who has sold to moderncoin had pr70dcam sets in pcgs and ngc when he bought the coins, there were no spots,haze, toning,etc. However later they developed on the pcgs coins, the ngc ones never had an issue

U mind sharing the camera setup to take these great pictures?
It sure seems like it. As I stated previously I saw many examples of heavily toned gold eagles (and again, I am NOT talking about copper spots/cherries) from 2006 and 2007. One guy in particular had a two different 1/10th age's with wild toning that he was asking $750 for the pair on.
>>> Are ngc slabs vacumn sealed??
I don't know, but no slab is truly airtite over the years. I've seen pics where people have submerged slabs and the coin stayed dry and other pics where the slab filled with water.
>>>I've noticed issues with the 2006 gold sets as well.
Yuuup. Check out the heavy toning on the reverse of this 2006 gold eagle at the bottom of this post.
>>>the ngc ones never had an issue
I have yet to see a heavily toned AGE in any other tpg slab. Out of respect for our awesome host I want to make it clear that I'm not stating that the slabs caused the toning, but rather I'm simply making the observation that there are a LOT of heavily toned modern gold coins in PCGS slabs while they're nearly non-existent in competitors. Until I read something from PCGS on the matter, that's all I will say about it.

I am using a Canon Rebel XS with a Canon EFS 60mm macro lens.
Mounted on a copy stand, using a remote shutter release and (3) 75W PAR30 halogen lamps.
The biggest help I have received is from some pointers from Todd at BluCC, a really good guy, and Mark Goodman's book.
Compared to these two, I have an extremely long way to go.
