I was asked to write a short item for a U.K. business about the high prices of today's new records. I ended up thinking they are not all that high. The Sam Goody's ad from 1973 at the top is for the Led Zeppelin catalog, that at the time consisted of five LPs. The list price was $4.98. The sale price (if you brought in the advertisement) was $3.49. Sounds cheap, no? Well, no.
In today's dollars that $4.98 list price is $29.21. The $3.49 sale price is $20.47. So really today's "average record" prices are comparable and not really high. Consider the prices of Blue Note's "Tone Poet" series or the "Verve/Acoustic Sounds" series that sell for around $34. These are better sourced, pressed and packaged than most 70s era records selling for a comparable price.
