It's just a question of color.

I just got my coins back from a recent submission and was a bit disappointed that 4 came back as QC. I totally understand that grading is totally subjective, including color. While I am in no way any kind of expert on color, I do like it if it has good eye appeal.
The following 4 came back as QC and I'm not totally sure why.
First is a 1944-D Jefferson. I cracked this out if an old Numistrust slab. I liked the strike and color.
2nd is an 1979-P wide rim SBA. It came out of a 3 coin set of first day covers dated July 2, 979 commemorating the 1st day of production for the new dollar
3rd is a 1956-D Lincoln that I removed from an original 1956 mint set
Last a 1930-D that I probably bought raw years ago.
Any thoughts, input, or education would be greatly appreciated.

i think they are all terrific. I have had personal problems with purple on my war nickels coming as AT or questionable color. The SBA I am unable to speak to, but looks great. The 1930 D is my favorite of the group
I wish PCGS would contact customers about coins that come back as "genuine, or QC, or details" and verify you want to pay the money for the trueview, or have that option on the paperwork

Real nice coins ... and to my eyes beautifully toned.
Interesting... I would certainly question the SBA and ask for a review... Cheers, RickO
The Jeff does give a little ??? on color to me also, but the rest look just fine to me.

i haven't seen/heard through all these years success rates for regular vs shield service, where the shield does the sniffer, which takes human experience and opinion out of the equation to 99%+.
that seems like it should work out as either a coin has contaminants or it doesn't., at least at the time of sniffing.
maybe some others can share their experience between the 2 services and the results for seemingly problem-free toner coins.
nice group.
.
Could the container that the coins were shipped to PCGS in have contaminants that were “sniffed “? Or is that a stupid question?
it is sure possible but the odds of the "container" having enough to fail a coin grading is pretty low.
.
The Jefferson and the 30-D Lincoln both look off to me but the other two seem ok. Graders are human and subject to certain thought patterns, if the first coin in the submission looks off then his/her mind has shifted from a neutral objectivity to one of suspicion and it may affect how the remaining coin are seen. I know its not supposed to be like that; each coin is graded independently etc.; but humans are influenced by visual cues.

Never a slave to one plastic brand will I ever be.
They graded this one natural toning. Go figure.

depending on the year it was submitted, all foreign coins go through shield service, which is the sniffer if my info is correct. and bonus true views on all foreign as well.
go pcgs!
.
the color on that Jamaican coin are quite vivid but during that era there was quite a bit of packaging that contaminated and toned the coins they held. the most common example is probably the 1971-1973 Canadian Dollars.
If there was a WTF button I would be clicking it.
Passing this “sniffer” does not equal guaranteed natural toning.
I don't think the Sniffer is used anymore. PCGS hasn't said a word about it in many years.
Secure Plus was introduced in the spring of 2010 as the "BIG announcement". Coin fingerprinting -- digital scanning, imaging, and archival. (Plus-grading was also part of the Big Announcement.)
Months later the Sniffer came along. It supposedly could detect specific foreign substances on coins (don't ask...some of them were utterly revolting). A second generation Sniffer came along in 2011. And then things went dark.
Secure Plus was renamed "Gold Shield" not long ago. It touts the same fingerprinting technology. Good stuff! But look around and you'll find no mention of the Sniffer.
From PCGS's website:
"With PCGS Gold Shield, each coin is imaged in high resolution, registered, and checked against PCGS’ vast proprietary imaging database. Our Gold Shield system benefits from artificial intelligence and machine learning, helping our graders quickly identify and remove counterfeits from the market. PCGS Gold Shield may then identify lost or stolen pieces resubmitted to us, ensuring your coin’s maximum value."
I'm not knocking Gold Shield. I like it. I wish all coins used the service. With the included True View (which PCGS never promised us...it just sort of happened) it is even better.

That would be a NO. No one that owns toned coins would consider that Jamaican naturally toned.
There’s an excellent chance that some of them would come back fine if resubmitted.
All obvious NT. To call the 56d 1c "at" is ludicrous IMO.
Hang in there. It's just part of the maddening game we play. Below is a 56-d which took me three times to holder. It has a faint blue tinge in hand and they ruled it questionable color. It now resides in a 66+RB holder. The highest graded example in red or red/brown. RPM FS-502



But I see no upside in doing so.
This can also be true.
All 4 look good to me.
You got boofooed.
from the TV's, this looks like something you can make in your windowsill.
The mint set coin looks like a mint set coin.
Maybe birds of a feather...
That would be a NO. No one that owns toned coins would consider that Jamaican naturally toned.
and that would be a NO but what's the use of continuing?? my hunch is that like many of the TV'd coins that are pictured here, this one only looks like that with the light at the right angle.
here's one of those Canadian Dollars, but you already know these are NT, right?? perhaps you should seek employment at PCGS so you can straighten all this out.
This is where the Jefferson came from. I don't know if these slabs over time cause a coin to tone like PCI slabs.

I wonder if one coin, possibly the 30-D, caused some amount of guilty by association for the other coins. Over the years I’ve had more success with my submissions when I leave out the coins that might throw shade on the others.
Sure, grading is somewhat subjective and inconsistent. Enjoy your coins, in or out of holders.

While this coin may be NT and it has been determined to be market acceptable color, there is one characteristic on the Jamaican coin that very OFTEN indicates AT.
It is not a vibrant color. What is it? If 'my question is not answered, l'll post images of it this week. T
The dirty blue that surrounds the word "Jamaica" is commonly seen on AT'd silver coins. More than that IMO, is the tracing around the design in yellow on the reverse. You just don't see the color abruptly stop like that. It's as though someone was coloring with a crayon, but in this case, a sulfur pen.
