A VERY TOUGH TO FIND Pickup session with guys from Elmer SNowdens band in Harlem's Nest Club. Solos galore (probably Rex Stewart on cornet, Not Ed Allen) Harmony 439. E- (it would be E but slightly rumbly surface.) 
I have been selling and buying 78s since 1974 and guarantee grading and packing. I have been co-owner of VJM Jazz & Blues Mart (founded in 1953) since 1990. VJM invented the standard 78 grading system. See below.

I ship anywhere, but because of increasingly aggressive and careless customs officials, overseas parcels must be insured.

The VJM Record Grading System is an internationally-used and recognized system for grading both 78s and LPs. It is used by virtually all serious record dealers and collectors alike, with an easily understood sequence of letters to show grades and a system of abbreviations to show faults and damage.

The VJM Record Grading System.

N (78)  As new and unplayed (there are virtually no 78s that can categorically be claimed to be unplayed).

N- (78)  Nearly Mint, but has been played. No visible signs of wear or damage.

E+ (78) Plays like new, with very, very few signs of handling, such as tiny scuffs from being slipped in and out of jackets.

E  (78) Still very shiny, near new looking, with no visible signs of wear, but a few inaudible scuffs and scratches.

E- (78)  Still shiny but without the lustre of a new record, few light scratches.  LP: Some wear, scratches and scuffs, but no skipped or repeat grooves.

V+ (78)  V+ is an average condition 78 in which scuffs and general use has dulled the finish somewhat. Wear is moderate but playing is generally free from distortion. Surface noise not overly pronounced. LP: Below average with scuffs and scratches on fewer than half the tracks. No skips or repeat grooves.

V (78)  Moderate, even wear throughout, but still very playable. Surface noise and scratches audible but not intrusive.

V- (78) Quite playable still, but distortion and heavy graying in loud passages. Music remains loud in most passages. Surface noise and scratches well below music level. LP: Lowest Grade. Audible scratches, etc. on more than half the tracks. Listening uncomfortable.

G+ (78). Grey throughout but still serviceable. Music begins to sound muffled. Heavy scratches.

G (78). Quite seriously worn and scratched, but music level is still higher than surface noise.

G- (78). Music still prominent, but wear and scratch damage extensive.

F (78). Most of music remains audible over surface noise, but listening now uncomfortable.

P (78). Unplayable.

NB: Damage to labels and jackets (LP) should be noted whenever present.
