This is inherently the issue. Given the lack of other resources and the dependency of the remaining ones on this primary (bad) data, the research options get thin real fast and the bad data becomes de facto gospel.
Given the amount of transactional data available - including specific buyer, seller, histories and general aggregate price data - I believe there’s a model that could be created to give a closer to realistic picture of value. But there’s no incentive for Discogs to do it. The damage is passed on to the market as a whole while Discogs collects their percentages.
Maybe it’s just a matter of letting competitors rise and force the issue. But until then, I’d take only take Discogs values with a grain of salt. Like a few others have said, you can’t stop uneducated consumers from paying a whackload and there’s no shortage of people with more cash than common sense or a shortage of people willing to exploit that.
Where it impacts us, as collectors (if only by habit, not as capital-c Collectors) is we will continue to be unable to get a reasonable estimate on the valuation of a collection, so that’s going to impact your buying, selling, and - if you’re real unlucky - replacement.
Anyway, take that for what it’s worth. Not saying anyone shouldn’t use Discogs, just saying maybe it’s time to stop holding it up as the standard and be aware of what you’re looking at.
I just think it's on buyers to do their own research. You have Popsike and discogs and gripsweat for a broader picture of what things sold at. You can look at discogs, ebay and search UPC codes to see if any smaller shops are selling copies of an album you want for an idea of what the album is currently selling for.
I also don't think the data is all that bad on discogs. obviously there are extreme cases like really rare records where one sale can completely skew the median prices. but the main issues IMO are:
A) people are uneducated on record buying. but they will learn quick enough once they get ripped off
B) People preying on those uneducated buyers
C) people are impatient and willing to pay a premium to get something "now" versus waiting for a repress
D) record companies and places like Newbury and VMP push severe FOMO on albums by creating a model of false scarcity. I am of the mindset that most records will get a repress unless there's something like uncleared samples on it or the band is just really not very popular.
I don't think it's really on discogs to fix any of those issues. I try to tell people as much as possible if there is any news about a repress for an album i see selling for crazy prices. in a lot of cases (especially with moFis and other "audiophile labels") most people buy the albums for crazy prices anyway because either they want it now or they are looking at them as investments that will only go up in price. i feel like records as collectibles/investments has been a relatively new, more widespread phenomenon and it wasn't a big thing when I first started collecting about 15 years ago. that is largely because of bullet point D above. I often see people paying a lot of extra money for just a color variant even though the same exact pressing can be had on black vinyl for 1/4 the price.
anywho, i do think things will correct back down a bit. i don't think vinyl is entirely a bubble now but the really high resale on kinda common albums may drop back down.
and as for the part about correct valuation of your collections, i think it's really fun to see those stats, but never really thought they were accurate. specifically because they don't take into account record grading. i could have an album that is "worth" $500 according to discogs, but if mine is a beat up copy with scratches, it's obviously not worth that. even median price doesn't really account for that so I'm sure my record collection valuation is off. Plus if I ever tried to sell it, I'd never get close to the median price.
