Dbx encoded discs

I have these three dbx encoded LP Discs:

dbx Recording technology Showcase Series   volume 1
Mark Levinson presents.....
a collection of individual musical instrument recordings and selections from jazz and classical repertoire


BOY WITH GOLDFISH
Heroic Fantasy for Soloists, Chorus and Orchestra
Based on the Hawaiian Legend Paintings of John Thomas
LEE HOLDRIDGE -- THE LONDON SYMPHONY ORCHESTRA


RUTH LAREDO
PIANO
24 PRELUDES, OP. 11     5 PRELUDES, OP. 74      POEM, OP. 32, NO. 1
by ALEXANDER SCRIABIN

I am not into dbx or LPs nowadays.   For some reason I have two of each.  One of each still in wrapping.   Are they worth anything? 

Cheers

I’m surprised that DBX was used for noise reduction on CDs, since CDP, by design (CD standard), has its own noise reduction by pre-emphasis and de-emphasis. Each CD provides "flag" that can turn de-emphasis on, but it is almost never used. The main purpose of it was to reduce hiss of the analog tape, but almost all recordings these days are digital. DBX encoded CDs would have value only for somebody who either doesn’t care about the sound or has DBX processor.

Pretty sure we are talking about Dbx  encoded vinyl records here not cd.
Even though the terminology of disc might be misleading.
At least that was my take on it.

According to Discogs they have 235 entries for dbx encoded material.
Including Supertramp, Cat Stevens, Heart, Moody Blues, J.Geils Band (lol!).
Fancy that.

So it looks like Discogs might be best resource for both pricing and as a catalogue.

@uberwaltz You are right I should have called it vinyl because when dbx was going around CD was not even invented yet and everyone then called vinyl either discs or records. Sorry for being so old fashioned and giving away my age.
