As the owner of Vols. 1 and 3 of, actually, the Living Stereo REEL TO REEL copies of the Robert Russell Bennett conducted re-recordings RCA issued between 1959-1961: they are in genuine stereo (if these are the same sources you're speaking of and not different ones lifted directly from the soundtrack of the 1952 miniseries?) and are great. I wouldn't think the originals would be more than $20 per volume in VG+ shape (because, unfortunately, it has been relegated to being called "elevator muzak" thesedays by people that don't respect the artistry of it).
If there's one complaint one might (possibly?) cite about the recordings, it's that: there are A LOT of authentic WW2 sound effects mixed in with the score....in that late 1950s, "ping pong stereo" kind-of-way(!). Some people might be annoyed by that or find it jarring because there was very little compression used it seems when, for example: there will be an orchestral track THEN -BOOM!- a klaxon horn will scream or a fighter plane will zoom across the speakers(!). It's gimmicky, but there's a certain "historical" sense of spirit it will evoke upon each listen.
