Yellow PCGS labels?

Sn3nut

I searched through the archives to try to find a definitive answer to whether or not PCGS ever made yellow labels. The best answer I found was from Bear back in 2001 - "A yellow label means that the slab has Hepatitis and jaundice. Its probably contagious, so wash your hands after you handle it."

Here is one I picked up at the FUN Bullet sale last night. It sure looks yellow to me ... not a faded green. Any thoughts, anyone?

I have a few of those and I was under the impression that they are a faded green label.

I have a couple but I just don't see how they can be a faded green. They are just TOO yellow!

Conder101 says they are faded green.

David Hall says he doesn't remember any PCGS yellow label slabs (but he doesn't remember some of the sample slabs they made either).

I have several yellow labels and they are NOT faded. Maybe different mixture of ink causing a yellow color but they are not green that was faded by the sun.

I'm still up in the air about them and they need more research. We have had several good threads on the topic and just search "yellow" or "yellow label".

No according to homerunhalllink

The thread where we discuss HRH's reply

"I don't think" is very wishy washy to me. Kind of like "I don't know" but not willing to admit it.

Can you post a pic of the whole slab, BOTH sides?

Glenn

Sure, I can later. The back looks exactly the same on both types.

Usually something that's faded does not fade so evenly. The edges are either more or less faded, etc.

They are just too perfect to be "defective" if you will.

Most likely is that the mixture was wrong and so many thousands were made like that and PCGS didn't care @ the time

Hanging onto to those yellow PCGS insert slabs is a good move as they are quite scarce, even rare. I have taken one of the yellow insert "tags" along with several green tags from previously cracked out PCGS slabs for chemical analysis.

Their prelimimary findings:

Unlikely a faded green tag pice of paper as they are of different color pigments.

They are testing to see if any of the green insert papers "fade" to yellow under intense lighting. More importantly, they are testing the yellow tag paper to see if it undergoes any further coloration changes under well lit conditions as well.

Found this one on eBay.

Yes, I vote for faded green. These label are now yellow, but once upon a time they were light green.

Does look like they fade

That is the progression of the various colors of yellow but how does that show they fade? I think it was different mixtures of colors at the factory over time and not fading.

Thanks Orville, please keep us informed on what the analysis turns up.

(great, what do I do if the analysis shows that it ISN'T caused by fading and there are over a dozen different colors of PCGS 4?)

I got a phone call from the lab. They noticed that the black lettering has faded along with the paper turning whiter whether the starting point of the paper was green or yellow. They see no evidence of green turning yellow. The green turns a faded whitish green but is somewhat splotchy.

They are still blasting the lights at four different levels during the day/dark at night plus a normal room lighting and a dark enclsoure for controls.

Cool! Keep us updated as they let you know. Thanks for taking the time and money to do this experiment.

Quality control being what it is from suppliers this could have been a bad batch that was originally green and turned yellow over time. If that is the case unless you have a green insert from the same batch of paper no amount of testing will prove anything.

Heywood

Does anyone with too much time on their hands know the approximate SN range for the different slabs?

(Assuming the SNs are date consecutive).


Coins in a dealer case under lights all day may fade faster than those in a collection/safe.
If it was fading, you should see some slabs that are green with SN between dates with "yellow" slabs.

If you have any yellows, post the SNs.

I'll check the 1-2 I have when I get home.

there is another thread on this topic and it has pics too

poorguy

This one is a solid yellow, not chartreuse like some I've seen.

Conder101

Serial numbers are NOT date consecutive. Explaination from PCGS is that each day a random SN "block" is assigned. The coins are consective for that day but a different block will be used the next day. And it is also probably a good bet that not all of a days submissions all go the slabbing/sealing room on the same day so that could jumble SN some as compared to label batch as well. n short there is no way to relate SN and labels to a particular order.

UPDATE!!!!!!!!!!!

<<<<<<<<<<I got a phone call from the lab. They noticed that the black lettering has faded along with the paper turning whiter whether the starting point of the paper was green or yellow. They see no evidence of green turning yellow. The green turns a faded whitish green but is somewhat splotchy.

They are still blasting the lights at four different levels during the day/dark at night plus a normal room lighting and a dark enclsoure for controls. >>>>>>>>>

I got another update. I went up to the lab and saw evidence that the green label paper has turned yellow. We changed the lighting to natural outdoor lighting and that has made the difference. There appears to be something in the natural sun light spectrum that causes some of the green labels to turn yellow!

Does this look pretty yellow?

interesting to see that it took science so long to "prove" what practical experience told everyone was happening. i would surmise that the effect is the same as what you'll see with curtains-----those hanging in windows with different degrees of sunlight will fade differently even if they're all from the same dye batch.

ipmman

That yellow label is absolutely fake. You should sell that coin for cheap right away. PM Me.

haha. my thoughts exactly. yellow and blue make green!

Science won't help you much if you don't ask the correct questions.

Yeah, those science guys are an uppity bunch.
