Vinyl pressings
by Love Unlimited · 1974

25 pressings came out in 1974, the album's first year, in 20 countries. Compare the label and catalog number on your copy, then the codes etched or stamped in the runout groove (the dead wax around the label): they are the surest sign of an early pressing.

31 vinyl pressings of In Heat are listed here, from 26 countries, released between 1974 and 2019.
The earliest pressings are from 1974, in US, UK, Argentina, Australia and more. One of them is 20th Century Records T-443.
Check the catalog number on the label (first-year pressings use T-443, BT 443, Se546, L 35257) and the codes etched in the runout groove, then compare them with the pressings listed above; for example, P M-443-AS X and P M-443-BS. Later reissues often keep the catalog number but change the label design or the runout codes.
It depends on which pressing you have and on the condition of the record and its sleeve. Early pressings from the album's home country in near mint condition are usually worth the most; common later reissues are worth far less. Scan your copy with VinylLens to see its value for every grade.
