What's it worth to you?

Among my 28,500 LPs, I have several dozen $300 to $500 (maybe more now) classical records of the Better Records variety.  An example is Backhaus plays Brahms on the original Decca versus the London and London STS later releases, a Japanese Decca and a CD release.  The original Decca has the best sound.  It sold a dozen times for $400 to $800.  I paid $1 back in late 1980s.  I would never have paid more than $35 for it.  It is not 35X better than the other versions.   Same with Reiner's early Also Sprach Zarathustra (original NM RCA).  No way over $35, now sells for $400-$700. 

Better records chooses the best pressing at a high cost for their number of LPs they had to purchase to find it, cleaning, listening time and labor.  Tom has brought over a few of his hot stampers decades ago when my system was in it's infancy and those LPs slaughtered my copies.  

My best friend has a rare jazz collection.  100s of his LPs are worth $100s-$500.  He paid $5 to $50, mostly $15-$25 back in the 2000s.  He is so glad to have those great LPs although now his digital copies are sounding very close to them at a fraction of the cost.  

No streaming for any of my friends, it's LPs and/or CDs.  

and 7,000 CDs and 7,000 78s.

I have a storage room adjacent to my custom built listening room which holds 18,500 LPs and 78s and the nearly all the CDs.  I have about 250 CDs in a rack in the corner of my listening room.  The LPs are arranged by genre, alphabetically.  2/3rds are on word perfect files by genre, LP, 78 and CD.  

The rest of the LPs are located in a storage shed (5,000) in two garage walls (2,000) and another 3,000+ in another storage off site (mostly opera & vocal-inherited of which I have 70% already, sometimes twice from another inherited collection).  

I do not have my records insured under my personal articles policy.  They wouldn't take it.  However, I do have all my audio equipment and furnishings above $250 (about $180,000) in it.  I do have a Nationwide Private Client HO5+ policy which is not the common policy HO3 and my agent said that my records would be covered.  After purchasing my home for $1,350,000 in 2019, my homeowner's insurance is now $2,450,000 plus a 200% bonus to replace/repair so $4,900,000.  That's so that the company could increase the premium (more than doubled).  My most precious recordings are in my house storage room.  

I've sold over 18,000 records in the past 30 years.  I have a rule, if I don't potentially want to hear a recording three times annually, out it goes.  

I could not replace my 78s or 1/3 of my CDs and LPs as they are rare or limited issues (500 to1000 each).  E.g. Marston, Romophone and Biddulph 1000 pressings with the Marston on a subscription basis.  750+ CDs on those three labels. 

I know, I have my limits and I'm well off.  I sold a terrible sounding MOFI disc, Lorin Maazel conducts Respighi for $295 when I saw a half dozen available for $350 to $550 (now Ebay has four for $200 to $471).  I paid a buck for it in a collection.  Yuck sound.  The DGG LP probably sounds better and sells for $12.  I sold a Ry Cooder Jazz MFSL Japanese Pressing LP Sealed for $350 to a dealer 20 years ago that I also paid a buck for as a discontinued item in the early 90s.  Four are currently listed on Ebay at $600 to $1000.  Sheesh!   I stick to my 3X per year restriction and sold a few expensive LPs.  Too bad I didn't buy all those sealed MSFLs when they were available so cheap.  

@tablejockey On popsike the highest paid last year was $300.  Otherwise, under $70 for many sales.  The Discogs listing is an outlier.   Sorry.

I love discogs, better than ebay.  I've purchased so many mint condition CDs at reasonable prices from the U.S.  Foreign shipping costs are prohibitively expensive.  I only bought one misrepresented LP (near mint was trashed) but the seller refunded the money immediately on notification.
