Promo records or discard bin?

A large quantity of Joe's record collection is comprised of vintage promotional (or "promo") records. These are records that were never intended for public sale or re-sale. 

Joe was comped many promo records, mostly from record companies, agencies and band managers trying to get their clients work. Joe would sometimes return from New York City with suitcases full of promo records. Many of these records have never been played.

So - do they have value, and how does one grade?

Promotional records are tricky to grade. For one, they are not all equal. 

They often come in different varieties...In the case of Joe's PROMO records, some promotional records come:

• packaged in a customized folder with photos, yet the record jackets are untouched by punch-holes or stamps; 
• other promo releases are stock releases with stock labels and are only designated by a corner punch-hole; 
• several promo releases are white label "promotion only" "not for sale" records that may-or-may-not have any punch-holes and/or promotional materials packaged with them.

Some of these versions could be highly valuable and others could be worthless.

It is my objective to spotlight all pertinent details with straightforward descriptions and multiple photos. Read carefully & inspect the images closely. 

The market and YOUR bids will determine whether these records have any value or not.
