Vinyl pressings
by Secret Service · 1980
Ye Si Ca / I Know was first pressed on vinyl in 1980. Every vinyl pressing is listed below with its label, catalog number and runout codes, so you can tell an original from a reissue.
8 pressings came out in 1980, the album's first year, in 8 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.

18 vinyl pressings of Ye Si Ca / I Know are listed here, from 12 countries, released between 1980 and 1981.
The earliest pressings are from 1980, in Sweden, France, Germany, Italy and more. One of them is Sonet T-10023.
Check the catalog number on the label (first-year pressings use T-10023, 101400, 6.12 969, SON 2704) and the codes etched in the runout groove, then compare them with the pressings listed above; for example, T-10023 A2 CR Tα and T-10023 12 CR Tα. 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.
