NGC is using the 10-point scale for coins from 1982 onward at the submitter’s discretion. 70-point grading is still available for these coins. According to NGC, a grade of 10.0 on the 10-point scale is equivalent to 70 on the 70-point scale. This seems simple until you try to convert other values.

Not so bad going from 10-point to 70-point scale. Just multiply by 7. So, a 4.3 coin on the 10-point scale is a 30.1 coin on the 70-point scale. This increases the number of possible numerical grades on the 70-point scale to 101 because that’s how many grades there are on the 10-point scale.

The real fun is going the other way from 70-point scale to 10-point scale where you divide by 7. So, an AU55 coin becomes a 7.857143… coin on the 10-point scale! Yup, definitely going to send all my modern coins to be regraded on the 10-point scale.

There is plenty wrong with it. If you are a collector who has hundreds of coins, as I do, this is an attempt to get me to spend tens of thousands of dollars to get a new number on every slab. Add to that the risk you take everytime you ship out a valuable item, and you have a hobby nightmare.

The grading services and some very empty headed collectors have asked for the 100 grading system for a long time. I don't know what is so great about the base number 100, but there people who think it will fix a multitude of problems. It won't. Overgraded coins will still get out of the grading room, and problems with pieces that have been played with will continue.

Add to that, the ridiculous waiting times we have now to get coins and paper money graded, and its a nightmare.

 

Oh, I think it's a horrible idea ... just a money grab. My comment was only about the ridiculousness of changing from one grading system to the other.

As Mom says: Stupid Is As Stupid Does. I know stuff, I saw the common sense movie.

 

I like the idea, 10 (or actually 100) point scale is much more logical than 70, but I don't like how NGC (or NGCX) did it...
It would have been logical to add the "old" grade also to the slab, so it would be easy to understand how it corresponds to "old grading system". The new grades are directly tied to old grades anyway, so it would be pretty much automated process.
And then in unspecified future, if people are used with "new grading", then drop the "old" one.

 

If something ain't broke, don't fix it.........

 

I worked in a B&M coin shop as a young 9 YO not yet recorded genius assistant, buying/selling/trading at an advantage relative to my boss.

We went to shows together where sellers would also give greater consideration/trust to a young individual, and we virtually never had problems with the cull/fair/about-good... system.

When the 70 point system was developed, we thought that was stupid.

We realized that the creators were generally a group of old sellers who probably never learned about the advantages of the base 100 or numeral system.

This new 10 point system is basically a seemingly greed system where only 10 numbers can generally be assigned, again by a similar group as the 70 point system.

You'd have thought they would have been familiar with, and considered the "Parker" system (https://www.google.com/search?client=firefox-b-1-e&q=robert+parker+100+point+system)!

Can't leave the last dollar just sittin' on the table.

 

I agree with what you are saying to an extent. I don't think that a 100 point grading system would solve any problems.

I do think that a base 100 point system is more intuitive and that a 70 point system is kind of an odd choice...but it has worked for a long time. I think because the world uses a 1-100 scale for a lot of things...it would seem more "normal."

Outside of that, I don't see a point.

 

"Just food for thought", the "decimal" (metric) system has been in documented existence for almost 20 centuries, as it easily allows conversion to larger/smaller units by simply moving the decimal.

I've been asked many times why a 100% perfect MS70 coin has that strange number, and all I can say is DUH!

However in a choice of "perfect" people/things, we seem to prefer "a 10".

Here are simpler thoughts: https://www.quora.com/Why-were-other-number-systems-developed-after-decimal-number-system

 

Yup, 10 little piggies or fingers is almost certainly the origin of the most commonly used number base. But numbers other than powers of 10 are used for maximum scores in all sorts of human endeavors. Why do dice have 6 sides? Fair dice with 10 sides are easily made. Why is the maximum SAT score 1600 rather than 1000? So, no need to apologize for using a 70-point scale for coins. 70 provides enough range without resorting to a decimal point or plus additions even though such extensions are often used. Better objections have to do with the way the 70 points are distributed. Why are 60-70 used for mint state? Why don’t we rate obverse and reverse separately? They can be very different. Yeah, I know the answer … KISS.

Not nearly as easily as cubes, at least with my shop skills...

 

Not that hard to make by hand. Example is in pic below. Start with a cylinder of plastic or wood. A little work with a grinder, rasp, file and sandpaper. But yeah, takes longer than 6-sided. For modern mass production, just as easy as 6-sided. Back in the day, 6-sided were easier to mass produce because every angle is right. And that’s likely the reason games require them.




Not too hard to make fair dice of any N possibilities. Take a relatively long cylinder (length 4 x diameter for example) and grind or cut it along the long dimension to have N flat sides of equal area (i.e. cross-section is N-sided regular polygon). Then grind each end to a smooth cone, N-sided pyramid, or hemisphere. These are called long dice. A pic of 4-sided long dice is below.

It's believed, I've Accugrade (ACG) slabs where both the Obverse and Reverse were graded!

Alan, I believe had the original "Slab" Patent, see: https://www.google.com/search?q=did...QABiiBBiLA-IDBBgAIEGIBgE&sclient=gws-wiz-serp

Stop making me look up words….

 

Two thoughts not mentioned already:
1. They use a decimal point. Therefore there are 100 available grades: it really is a 100 point scale normalized down to a maximum of 10.0 to be compatible with other graded collectibles.

2. Their descriptions of grades no longer mention circulated or uncirculated. Since this is a grading criterion that is a judgement call that arbitrarily draws a line between AU and MS grade ranges, they can sidestep cases where an AU 58 is clearly a better coin than an MS62.

 

I keep forgetting that not everybody's been indoctrinated, despite our* best efforts.

* Hexadecimal numbers are better suited for computers, because they break up more evenly into groups of bits and bytes and "words" that computers use. Plus it gives you more cool numbers to choose from, like 2B00B1E5 and DEADBEEF.
