What You Don't Know was first pressed on vinyl in 1989. Every vinyl pressing is listed below with its label, catalog number and runout codes, so you can tell an original from a reissue.
27 pressings came out in 1989, the album's first year, in 14 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.

29 vinyl pressings of What You Don't Know are listed here, from 14 countries.
The earliest pressings are from 1989, in US, UK, Australasia, Australia and more. One of them is Arista AD1-9837.
Check the catalog number on the label (first-year pressings use AD1-9837, AS1-9836, ADP-9845, 112 354) and the codes etched in the runout groove, then compare them with the pressings listed above; for example, A-1 ADI-9837-SA HRM-1 MF and A-1 ADI-9837-SB HRM-1 MF. 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.
