Let's just say that you are a TPG who has been in business 15 or 20 years. Maybe over that period you have mostly been been quite accurate with your grading, but occasionally you have had periods of very lax (easy) grading followed by "oh my god, we're losing credibility, let's be really stingy with grades". How do solve we solve the credibility issue and erase all of those previous miscues?
Let's completely change the grading scale and then everybody will submit their coins, including those pesky coins that were badly graded, for regrading under a new scale that nobody can associate with any previous scale. We can fix our mistakes then and make money while doing it.
Voila! We're off the hook!

Grading is subjective. You can have 70, 100, 500, or 1000 point scale. Do you honestly believe changing the scale is gonna "fix mistakes"?
and it sets us apart from practitioners and consultants. Gregor
If they (the TPG services) go to a 100 point scale, there will be a one-to-one mapping of the 70-point scale on to the 100-point scale (e.g. 60-70 will map directly to 90-100).
That's not necessarily true. A 67 is 95.7% of the current max grade of 70; that is 67/70=.957. Assume that a group of 67s are "accurately" graded. I imagine that any TPG service will grade some of their 67s that are resubmitted as 95 and some as 96. (Others may even grade 94!)
Those that are "downgraded" will decrease in value, and that's when the hooting, howling and moaning will begin.
I don't see any value to collectors in changing the grading scale; it will lead to enormous confusion in the hobby. TPG services may increase their business in the short-run, but longer-run I believe it will badly hurt their business.
Honestly the TPG's are somewhat shielded from grading errors or inconsistiencys because 'grading is subjective'. If they were able to be held truly accountable and it would be a financial burden to them if things were graded wrong and determined to be wrong by some sort of independent judging panel, they would be looking to go to maybe a 50 point or 30 point scale to reduce the margin of error.
Just some random thoughts. The current scale has worked for many years and is fine!

Gerry's math is fine, but the new 100 point system is not a ratio scale in reference to the 70 point system.
I think there was a post by HRH that showed what the mapping between the two would be. It is very simple and each current grade has an assigned 100-point scale grade. All that happens is you take your 60 and call it a 90, your 65 and call it a 95, your AU58 and call it an 88. I don't think they will assign a AU99 just as they would not assign an AU59. There are plenty of inbetween grades that are not used now and they will not be used in the proposed system. I the lower circ grades, there are sections of number skipped to make up the difference.
The aspect of regrading fees and whether coins will be regraded or just assigned the corresponding grade are certainly worthy of discussion. As far as the sliding scale goes, the 100 point system is directly mappable to the 70.

Well you sucessfully quoted me, but you obviously didn't understand me. The 100-point scale will not use all 100 values, and thus mathematics you showed is wrong because of that fact.
Sorry if I misinterpreted what you said. Ditto for you, ecos. Are you saying that if one submits their coins for reslabbing by a TPG service under a 100-point system, every MS67 will be automatically be converted to a MS97 and every MS66 will be automatically converted to a MS96, etc. etc.? In other words, there will be no regrades - only a direct translation?
Also, looking at submitting coins raw, does that mean that anything that used to be graded 67 will "normally" be graded 97?
If so, what is the point of going to a 100 point scale, at least for mint state graded coins? Just asking? Maybe there is something(s) I'm missing.
Also, Steve, what does this mean: They wil just be using fewer numbers than they currently use. There are 11 numbers from 60 to 70 and 11 numbers from 90 to 100???
