Vinyl pressings
by Horslips · 1977
Aliens was first pressed on vinyl in 1977. Every vinyl pressing is listed below with its label, catalog number and runout codes, so you can tell an original from a reissue.
18 pressings came out in 1977, the album's first year, in 9 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.

21 vinyl pressings of Aliens are listed here, from 10 countries, released between 1977 and 1979.
The earliest pressings are from 1977, in Ireland, UK, US, Australia and more. One of them is Horslips Records MOO 14.
Check the catalog number on the label (first-year pressings use MOO 14, DJF 20519, DJLPA-16, L 36621) and the codes etched in the runout groove, then compare them with the pressings listed above; for example, MOO 14–A2 TB A PORKY PRIME CUT and MOO 14–B2 TB. 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.
