while an interesting question, the question is "how do you get all dealers to use the same grading methods" and the answer is "you can't"

Jon Warren tried that 15 years ago or maybe 20 and dealers are resistant to working with others frequently.

One auction you cited only uses a proprietary grading system that goes to fine and no farther, while the rest of us use a system that goes to Mint on the "C" scale
This issue was discussed on APF once.
managing a grading system is only useful if everyone or a majority of everyone agrees, and some people will refuse to go along with any such system regardless of any agreements with the majority populace.

It also is not uncommon for a resold poster to be regraded and go downward as the poster has been handled since it was first sold

one good example of regrading by different dealers is cards that have already been graded by CGC and there is a really good example cited in an APF thread where some Beatles cards were graded 9.0 (NM-) to 9.8 (NM-M) and were sold on MoviePosterExchange.com. Later the same cards were sold elsewhere and graded Very Good which I grade at C-5 (previously graded by CGC at 9.0) and Very Good to Fine which I grade at C-5/6 (previously graded by CGC at 9.8). Clearly there is a disconnect here.

obviously, the proprietary system used by the one seller is incompatible with the C grading system used by CGC and the rest of us (MPB, MPE, Heritage all use a C system).

the discussion on APF is at this link

then you get to eBay sellers. Not all eBay sellers are pros. Many are "Weekend Warriors" who sell on eBay for extra money or collectors looking to thin their collections. How they grade has nothing to do with how Pros grade and trying to get them into a standardized system is a great difficulty

from my perspective, grading is a subjective practice with most people and solid grading systems require considerable learning by those involved CGC exists not because people can't grade, but because it was difficult to get people to otherwise agree with grading and when selling a Superman #1, there is a considerable price difference between C-6 & C-7, so in comic books they have chosen to let a 3rd party be the arbiter of the grading. Considering the resistance to CGC in the poster hobby, I find it unlikely that grading practices will merge in this hobby.

the reality is that grading is just a guide, by any seller. If you buy from anyone regularly, you should be able to decipher the meanings of the individual sellers grading systems and no seller - no matter how much anyone wishes to try to tell you different - grades the same way twice except by luck. All of our gradings take in a list of considerations to arrive at a conclusion. As buyers it is necessary to understand our meanings, at least until the day comes that everyone agrees on what system should be used, though clearly the majority agree the C system is best

I am using Heritage as an example, but I hope nobody uses that as an excuse for sniping, as I think we all suffer from a mote in the eye here. In a recent auction HA had this poster - <http://movieposters.ha.com/c/item.zx?saleNo=161410&lotNo=52344>http://movieposters.ha.com/c/item.zx?saleNo=161410&lotNo=52344.

I noticed it was the same poster as previously sold by them - <http://movieposters.ha.com/c/item.zx?saleNo=161253&lotNo=50302>http://movieposters.ha.com/c/item.zx?saleNo=161253&lotNo=50302.

The only difference was that the grading had moved from 'fine' to 'fine+'. I contacted HA to enquire about that and received a reply from Grey Smith. 'If items are reconsigned with us, we have a team grading and evaluating each lot for condition ignorant of its previous sale. Naturally, grading will always be subjective to a degree.' I replied that while I accepted grading as subjective I did not think it unreasonable to expect consistency from the same source, and it would appear that the present team is more lenient in its appraisal than that of the recent past, as is evidenced by yet another poster previously rated 'fine-' which has now been promoted to 'fine'. <http://movieposters.ha.com/c/item.zx?saleNo=161410&lotNo=52506>http://movieposters.ha.com/c/item.zx?saleNo=161410&lotNo=52506

I received no reply to that.

Now I appreciate that we are dealing with quite fine distinctions here, but grading is important. Having large images to view is all very well, but it does not show everything. Wrinkles do not always show well, and there are no images of the back of the poster so the amount of tape or writing there relies on description.

The main problem I find, though, is one of comparison. Is HA's 'fine' the equivalent of EMP's 'good' (and surely 'good' meaning 'not very good' is one of the worst anachronisms)? HA does at least assign a numerical value to the rating, and other sites such as MoviePosterBid and MoviePosterExchange do use numbered grading, but there still often appears to be some difference in values as, for example, MPX seem to be very critical and often have posters as low as 2 or 3 which I expect others might have as a 4 or 5. The majority of eBay sellers are quite happy to describe their wares as 'excellent', and major auction houses such as Christie's simply have an A,B,C rating system.

I like the <http://iguide.net>iguide.net numerical system, and should something like that not now be accepted as an approved standard? CGC and third party grading would seem to have limited appeal, but there is no reason why a unified system cannot be applied. It is surely long overdue, as Alan Adler's post of Jan 2006 demonstrates -

  A unified grading system would be fantastic.
It will happen - just a question of when.
Look to Overstreet's comic guide and the pages on grading comics and
find a useful and well-organized list of criteria that has worked well for the comic world.

Overstreet even has a book out devoted only to grading of comics.
It has photos of every grade - using a number scale - 1-100 I think -but could be wrong.
Check it out at the bookstore or library.
There is no reason this can not be accomplished for movie posters -
Even though there are a number of sizes - the same rules set forward for grading movie paper can work for all with minor notations.

Eight years later but still it hasn't happened, but the idea must be appealing. At least we would then be able to view and compare posters based on mutual assumptions, and also be able to compare the rigour of the dealers in their appraisals.
