The best advice you can get is to take a few of those old records to an antique store where you can play them on a phonograph. What you will discover, they do not sound anything like what we today consider hi-fi. Modern HiFi is all about making you feel like you are in the recording studio. The phonograph does something completely different. It makes you feel like the singer is there, inside the phonograph! There is nothing else like it. This is what we have lost. This is the true value of these recordings, and yet it is completely lost when played back on high end gear. The only way to fully appreciate them is to hear them played back on a phonograph.
As odd as it sounds they aren’t worth much- yet they are priceless.
