Charles Mingus--Pithecanthropus Erectus, Mono Atlantic 1237. With Jackie McLean (as), J.R. Montros (ts), Mal Waldron (p) Willie Jones (d).  Recorded in New York City, Jan. 30, 1956. On the dead wax: Stamped "AT" both sides, on 1st Side stamped "A" on the 2nd Side stamped "E." I am not familiar with Atlantic's conventions for indicating 1st pressings, but this is more than likely the 1st press.
Sound Quality: NM ... The sound quality is fully intact and nothing less than superb--brilliant, vibrant, compelling. (Not available on CD.)
Vinyl: VG+ ... The A-Side starts with some seconds of surface noise and there are two spots with a few low-volume consecutive ticks. Most of the last third of the side plays without problem, but before that there are frequent but truly barely-audible little ticks present. If you are not specifically listening for them (as, unfortunately, I must) it may well be that they will go largely unnoticed. Overall: VG. The B-Side starts with about three seconds of surface noise and there is one short area with some ticking, again of very low-volume. Outside of that short segment the side plays just about perfectly. Overall: VG++ Visually, the is a longish line on the A-Side which, however is superficial and isn't responsible for any problems (and won't be--see my note on visual grading at the end of the page) since it is most definite where the record plays best--the last third of the side. The B-Side has a problem spot on the first track which is responsible for some light ticks. Overall, the vinyl looks quite lustrous and fresh with hardly any blemishes beyond what has been mentioned. This appears to be record that has been played only moderately. 
Covers: Excellent... Thick cardboard jacket. Just a spot of fraying on two corners and some age-related discoloration on the back cover. Otherwise very nice with no splits, no ring-wear and the classic front graphic is bright, glossy and new-looking.
Combined shipping is always available with no mark-up--you just pay for what it costs to ship (and of course the more disks the less per record). Packaging includes new audiophile inner sleeves, new outer sleeves, cardboard padding, bubble-wrap and a thick cardboard record box.

It disturbs me that record buyers do not to insist on, or even seem to prefer, play-testing to visual grading. I believe that visual grading (although necessary) is totally insufficient for grading a record.

Why Visual Grading...Some dealers insist that they can do it very accurately (after years of experience, etc)... But I don't believe it. The fact is that play-testing is very time-consuming. It involves not just the actual playing of the record but the preliminary cleaning, which is crucial and time-consuming in itself. For large-scale dealers this is an insurmountable obstacle. Hence the best thing, from their point of view, is to foster the myth that visual grading is fine. It also has the very important added benefit of protecting the seller since if a record looks nice but is full of ticks the seller has a defense—it looked NM- so I graded it NM-.

Why Visual Grading Doesn't Work... One reason visual grading in general can't work is that the quality of the vinyl is invisible to the naked eye. And there was a steady deterioration in the quality of vinyl used from the 1950s to the late 1970s. Instead of pure new vinyl, by the end of the LP era, record producers were using recycled vinyl, old tires or anything else that could be re-processed. Most new records from the 1970s have ticks baked into the vinyl, sometimes a whole lot of them... (In addition, vinyl records became exceedingly thin in the passing years, another problem).

Another Reason Why Visual Grading Doesn't Work... Scratches on the vinyl are, of course, visible and cause consecutive clicks or pops. But low-volume ticks and slight background noise are, by far, the most common defects and it is very, very hard to determine whether a light mark on the vinyl will affect the play-back without listening to the record.

What Marks on the Vinyl Mean and What Buyers Need to Understand...If a seller says that there are various marks on the vinyl but they do not affect play, most buyers immediately downgrade the record. The only conceivable reason for this is that they believe that somehow, with additional playing, the very superficial hairline scratch will become deeper and start to cause clicks. I have seen no evidence to support this view. If one uses a properly-calibrated good-quality cartridge/stylus (set at less than 2 grams) I do not believe that non-sounding marks can “become” clicks or background noise, for the simple reason that the stylus is below the level of the surface defect.

Lack of Information Should Not Be Rewarded ... I have seen this time and again: A visual grader will say “Just superficial paper scuffs” grade it NM- or VG++ and this copy will be preferred to that of the seller who also grades it VG++ but says it plays with occasional ticks and a couple of seconds of low-volume background noise. To me this is pure nonsense. Buyers are paying a premium to a seller for withholding information. The fact is that almost every used record plays with some ticks (and quite a few brand new ones, too). Not knowing that (by not listening to the record) should not be a reason for paying significantly more to a seller.

The Wonderful World of Visual Grading ... Most of the terminology used by visual graders has very little specific meaning. Here is an example from a clearly honest seller, but what could it possibly mean?... “RECORD CONDITION: VG (LIGHT SLEEVE MARKS).” (This record sold for $100 on 17 bids.) On the other hand, you can find innumerable examples of the following: “RECORD CONDITION: NM- (LIGHT SLEEVE MARKS).” What does this imply?

I suppose it implies Caveat Emptor. Comments are welcome...
