Vinyl pressings
by Dinah Washington · 1959
What A Diff'rence A Day Makes! was first pressed on vinyl in 1959. Every vinyl pressing is listed below with its label, catalog number and runout codes, so you can tell an original from a reissue.
14 pressings came out in 1959, the album's first year, in 3 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.

44 vinyl pressings of What A Diff'rence A Day Makes! are listed here, from 10 countries, released between 1959 and 2026.
The earliest pressings are from 1959, in US, UK, Canada. One of them is Mercury MG 20479.
Check the catalog number on the label (first-year pressings use MG 20479, SR-60158, MMC 14030, SR-C 60158) and the codes etched in the runout groove, then compare them with the pressings listed above. 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.
