So I have about 20 LPs in Discogs with median valley north of $50.00. 15 of 20 are reissues. Many of the reissues done in the 1990s and 2000s of classic 50s - 70s rock, jazz and classical by such labels as Analog Productions, DCC, Mobile Fidelity, Classic Records, etc, can easily fetch between $100 and $300. Reasoning is 2 fold: (1) they were pressed in very limited quantities (i.e., usually runs of 3,000 or less) and (2) can often match of surpass an original 1st pressing in sound quality. Remember - a lot of those records of that era were mastered for people with shitty turntable that couldn't handle the high notes or the bass. An engineer mastering for a modern hi-fi deck doesn't have to worry about that chit. Also, take my Mobile Fidelity reissue of Miles Daves KOB which has a $100.00 median value. An OG mint Columbia of that album from 1959 would probably be like $1,000.00 and the reissue sounds just about as good.
