Test Pressings, Promo Copies and White Labels: How to Recognize Them and What They Are Worth

What test pressings, promo copies and white label promos are, how to recognize them from stamps and labels, what makes them valuable and how to spot fakes.

What is the difference between a test pressing, a promo and a white label?

A test pressing is one of the first few records pressed from new stampers so the plant, the label and the artist can check the sound before production starts. A promo copy is a record given away free to radio stations, DJs and reviewers to publicize a release, and a white label is a record with a plain or white label, which can be a test pressing, a promo or an unofficial club pressing.

All three were made in smaller numbers than the copies sold in shops, and some contain music or mixes that never reached the stock release. That is what can make them valuable. It does not make every one valuable: a promo of a record nobody collects is still a record nobody collects.

Test pressings

Test pressings are vinyl records pressed from production stampers and are physically almost identical to stock copies. The difference is the label: usually a plain or generic one, sometimes with TEST PRESSING printed on it and blank lines filled in by hand with the artist, title, catalog number and date. They normally come in plain white sleeves, sometimes with a label copy sheet listing what the finished label should say.

Runs were tiny. Unless they doubled as promos, test pressings were rarely made in more than about twenty copies, and often only a handful. At Decca in England, for example, three test pressings went to the cutting studio every time a plant received the first stamper from a new lacquer. Decca's own test labels were color coded, blue for mono, and carried a ring of strobe bars for checking speed, with the matrix and catalog numbers written in by hand.

Many were thrown away. A former Decca mastering engineer recalled scrapping them because the studio received so many, which is one reason originals are scarce today.

Acetates are not test pressings

An acetate (in the industry, a lacquer) is a lacquer-coated aluminum disc cut one at a time on a lathe, before any stamper exists. Acetates are two to three times heavier than records, older ones often have a second hole near the center for the lathe's drive pin, and the soft surface wears out quickly with repeated play. A test pressing is ordinary vinyl that plays like any record. Labels on both are often handwritten, so check the weight and the material before you check the writing.

How to recognize a promo copy

Record companies marked free copies so they could not be returned or sold as stock, and they did it in several ways:

Rubber stamps
Stock copies stamped on the cover or label with wording such as Demonstration Not for Sale. In 1979 Jay Jacobs of Knox Racks in Knoxville, Tennessee told Billboard that manufacturers found it easy enough to stamp that phrase on their promotional albums.
Stickers and printed text
A promo sticker on a stock jacket, or a line such as promotional copy not for sale printed into the regular label design.
White label promos
In the US, a special promo label with the same text and logo as the stock label but on a white background. Most US labels eventually adopted it. Decca used pink promo labels in the 1950s before switching to white.
Punched or cut covers
In the 1960s and 1970s Capitol often used stock albums with FREE or PROMO punched through the cover, or simply a hole punched in a corner, instead of a white label.
UK A label demos
UK promo records from the 1950s to the 1970s on company labels with a large A (to show which side to play), often with the planned release date printed on the label.

Promo or cut-out?

A cut corner, a punched hole or a notch in the spine does not always mean promo. US record companies used the same marks on unsold stock returned by shops, which was then sold off cheaply as cut-outs, and 45s were often drilled through the label or stamped C.O. Because labels also used these marks on promos, a hole alone cannot tell you which you have; a promo stamp, a promo sticker or a white promo label is the stronger sign.

White labels

White label means different things in different scenes. In US collecting it usually means a white label promo (often shortened to WLP), pressed in a few thousand copies per title. It can also mean a test pressing, or a dance music 12 inch with a blank label: producers pressed small runs, often fewer than 300, to test tracks in clubs, and labels such as Warp started out selling white labels to record shops. Some white labels are bootlegs with uncleared samples or unauthorized remixes, which is why a blank label on its own tells you very little.

What makes them valuable

Demand for the artist comes first. Beyond that, collectors pay for difference and for earliness. Some promos and test pressings contain music the public never got: a few test pressings of Bob Dylan's Blood on the Tracks (1975) have the original recordings he later replaced, test pressings of the Beach Boys' Holland exist with We Got Love instead of Sail On, Sailor, and some promos of The Who Sell Out gathered all the fake commercials together. After US labels dropped mono LPs in 1968, some kept sending mono white label promos to AM radio into the early 1970s, sometimes in very small numbers.

Promos were also among the first copies pressed from fresh stampers, which is why many collectors seek them for sound. The catch is condition: a lot of promos were played hard at radio stations, so clean copies of promos by bands such as Cream, the Yardbirds or the Who are hard to find.

A few have made big money in public sales. A test pressing of Aphex Twin's unreleased album Caustic Window, left with just four people, sold for $46,300 on eBay in 2014 to the Minecraft creator Markus Persson. Advance copies can matter too: about 60,000 promotional copies of the Beatles' Yesterday and Today went out with the withdrawn butcher cover, and many of the first state butchers that survive were kept by journalists, radio stations and record company executives. Test pressings of Bruce Springsteen's Born to Run (1975) went to radio in a script cover, with the title in handwriting-style lettering; several hundred were sent out, and collectors seek them today.

Fakes and how to avoid them

Plain labels are easy to copy, which makes this a risky corner of record collecting. Counterfeit acetates are fairly common, most often Beatles, with fake EMIDISC or Apple labels and artificial aging, and some have sold for three and four figure sums at auction. Collectors disagree on test pressings: a site devoted to the Rolling Stones on Decca reports that collectors who specialize in test pressings believe at least half of those offered for sale are counterfeit, while a US dealer finds counterfeit test pressings relatively uncommon outside unreleased titles.

Protect yourself the same way in every case. Check that the runout matches a real cut of that release (the matrix number and cut suffix should exist on stock copies or be documented for that test pressing). Be wary of promo stamps on a jacket that is otherwise a later stock edition, and of handwriting that looks too neat or too new. Ask where the record came from, and buy expensive pieces only with a return guarantee.

Reselling promos is common, and recalls of promos are extremely rare. In the US, the Ninth Circuit ruled in UMG Recordings v. Augusto (2011) that promotional CDs a label had sent out could be resold, despite their promotional use only wording.

Checking a record you think is special

Look first at the label: printed TEST PRESSING text, a white promo version of the stock label, a promo stamp or a handwritten label. Then read the runout and compare it with the known pressings of the album; a test pressing should share its matrix numbers with an early stock pressing or be documented as a separate cut. Check the jacket for promo stamps, stickers or punch holes, and note anything that differs from the stock release, such as a mono pressing or a different track list.

If the runout matches the regular pressing, VinylLens can identify it from a photo of the center label and show its value for each condition grade; for a true test pressing or acetate of a collected artist, ask a specialist dealer or auction house before you price it.
