Me too.
Some ambitious quant should develop a "vinyl price index". 😄 Something analogous to various crypto indices, S&P Global Luxury Index, fixed-income (bond) indices, etc. Maybe it already exists, but I'm not into vinyl and haven't seen anything.
There's already a luxury watch price index, for instance, but that was probably easier to set up since it uses 60 models from 10 well-known brands.
I'd be interested in seeing graphs of a "vinyl index" vs. luxury watches, housing prices, crypto, etc.
[Added] Scarcity of the underlying vinyl seems much more important than the art. For instance, Alan Silva's 4-CD "Treasure Box" package doesn't sell at much of a premium to the 4 plain vanilla CDs. Hmm...maybe I should buy a bunch of the Silva boxes? 🤣...No way!
