Any thoughts on trying to correlate your scoring system to the marketplace? Toned coins are difficult to value and being able to say a particular coin is in line with real transactions in a price range may be helpful. One problem with this would be that the number of data points for recent, verifiable transactions for a particular date and type is much lower than the number of toned coin pictures available.

So much of the value is associated with the type of toning, specific colors, amount of coverage, how it plays with the luster (that True Views frequently do not capture due to the hot lights) and how many examples of nice toners exist for a particular date/mm...not to mention the demand at any given moment between bidders, not to mention the grade. Way too many variables in my opinion.

Lots of factors for sure. My initial goal was just to quantify toning, and then slowly chip away at the rest of the mysteries involved with coin pricing and eye appeal. Uphill battle but having fun taking it on.

One potential issue could be that if the program is pulling its AT/NT determination from graded coins, it relies on coins graded as NT by PCGS actually being NT and those graded as AT actually being AT. There are undoubtedly many silver eagles in straight-graded PCGS holders that are AT, for instance. However, it seems to be doing a pretty good job.
I would be interested to see the results on AT coins with less intense colors.
Here are these results. I actually believe that the ASE is naturally toned. It was placed in one of those crinkle-wrapper shipping containers for quite some time. I've handled and seen these straight grade. The others, not so hot.
@Rexford said: @treybenedict Would you be able to run the group I posted earlier when you get the chance? They’re AT and would be a good test.
Furthermore, I think it's interesting to look at the graphs for AT/QC coins versus NT. They are drastically different and usually display a weird color mush. This is the toning progression happening pixel by pixel. The ASE forms the "E" which we talked about previous in the forum posts.
Curious to see how my other dimes do. Also wondering if the new 46 S pic will register differently. I see a new too much Orange detected on @rexford coins, so now Im wondering how my 48 D will turn out. It looks NT to me , but is extremely orange.

This only gets triggered when specific colors are detected. It has been implemented for a couple of days.

Alright, let’s see if we can break the scale:
Totally Nuclear! Amazing coin. I think this is the highest rating so far in the thread for a US coin. There was a proof earlier that received a 69, and the example Morgan rated 70. Nonetheless, stellar!

So this is a naturally toned coin?
According to the analysis yes. It seems on par with ASE’s from that era. I’ve had a couple like that. Cardboard, Velvet etc can make it tone wildly on both sides.
I understand somewhat, and the kid inside me leads me with many questions.
Here's one that has been on my mind as it's crucial in my research.

Reason being is, stability is a very crucial quest.

I like the concept, Trey. Keep at it. Am not quite sure how this would fit in between the TPGs and CAC, but I like the idea of an algorithm comparing color progression to that of a person.
I'm just throwing this out there, because if it's on my mind too long, I want it deleted.
"Could this be the next chapter in a book, with CAC being the previous chapter ?
Holy algorithm, Bubba !!!!!!!!!
What a quawinkeedink. (coincidence)
Wow, just found this cool thread! And I actually own that end roll toned 1884-O Morgan in the original post. When you get a chance, can you run a scan on my icon coin below? I have plenty of other toners if you want to run your program on them.

Awesome! That 84-O is the highest-scored coin to date. The colors are amazing.
I'll run this for you after we deploy our public preview website. ~1 day ish from now.
No offense but I’ll trust my eye over this algorithm all day long. I like the concept of computer aided coin grading for wear and pmd but not this concept.

Your not on a clock here. I am kindda in that spot, I have to post this tonight according to google. My files turn into pumpkins

No tech. worries. When you can. I'm trying something which "could" help both of us.
This coin was found in pocket change. I think the large spot on the reverse is the suspect (?) being solid, compared to the obverse pastel style of color. I have a few with that exact mix. (Color).
In the byepolar book it's 320 I think...? maybe 420 ?...anyway I would like to compare both mix's.
This will be the first of three coins.
No hurry, Bubba

This is likely corrosion rather than toning. I'm sure a version of this CV script can be used to decipher "problem coins" as well.
Demo website and a special surprise coming early next week. I wanted to save the demo website in conjunction with another release. Some already may have heard what is coming soon Building until then so I'll be a bit quiet.

Did this one real quick because the graph interested me. Notice how it is atypical from others in the thread (no color progression on HSV). Agree with our hosts here.
I think this is interesting work but would expect it to meet quite a bit of resistance. The topic of tone, AT, QC, and NT is very subjective and when the results from this system start to question the color I'd foresee collectors being quite upset. Some in this thread have already expressed as much.

Resistance will always be met when change is in view. An uphill battle I am willing to tackle for transparency of the collector
