It's just one example. There are several UK sellers who regularly sell common records for many tens of pounds. I'm not talking about rare discs. I'm talking about discs that you could find in any charity shop a decade or so back. The more interesting things can hit £100, and by interesting, I mean something that you'd have to look a bit harder for in nice condition - they're still discs that many (most?) normal collectors will have seen.
Yet meanwhile on the facebook "78 rpm records & cylinders fan group" there are collectors buying much rarer (and, in my opinion, far more valuable) records for 50p each. Which is about what I would pay

I understand sellers who sell hard to find records for tens, hundreds, even thousands of pounds. I get that. While I wouldn't pay it myself, for someone who really wants that record during their life time, they have little choice.
But honestly, 40s and 50s records that sold by the million going for £20? Christmas 78s going for £30-£60?
Who is spending that money?
Cheers,
David.
P.S. though I noticed that record players from the 1960s and 1970s, even 1980s, are now often heading over £100 while many gramophones struggle too.
