What does “runout markings” mean?

What it means

Runout markings are the hand-etched or machine-stamped inscriptions found in the dead wax area—the smooth, ungrooved space between the final groove and the record label. These markings are not part of the music; they are manufacturing data. They function as a fingerprint for a specific pressing. This data includes matrix/runout numbers (e.g., A-1/B-2), which denote the lacquer cut and mastering engineer, and sometimes additional symbols or text indicating the pressing plant or release date. For the reseller, these markings differentiate between a common commercial pressing and a rare variant, such as a test pressing, a promotional copy, or a specific regional issue.

What it does to price

The presence and nature of runout markings directly affect value. A standard, easily identifiable commercial pressing sets the baseline value. Markings indicating a first pressing, an early lacquer cut, or a specific mastering engineer (often noted in the matrix numbers) can increase value by 1.5x to 4x compared to a later, re-pressed copy. Conversely, poorly etched, smudged, or completely absent markings can signal a low-quality pressing or a generic reissue, depressing the price. For example, a record with confirmed, clean "First Pressing" matrix identifiers might fetch $30 more than the same record lacking that specific evidence.

How to spot it

Inspection requires a bright, direct light source and a magnifying glass. The markings are located in the dead wax, not on the label. Key tells include the specific alphanumeric sequences (matrix numbers) and any hand-written identifiers. Sellers should provide high-resolution, close-up photos of both sides' dead wax. Common issues include accidental smudging during cleaning or poor mastering where the markings are faint. Fakes are rare for the markings themselves, but misidentification—assuming a common pressing is rare based on superficial markings—is common.

Buying smart

Paying a premium based on runout markings is justified when the markings clearly indicate a verifiable first pressing or a highly sought-after variant (e.g., a specific colored vinyl run). If the markings are ambiguous, faded, or only vaguely suggestive, the premium is unwarranted. A fair deal involves the seller providing clear, verifiable evidence matching known pressing databases. If the markings are present but do not correlate with known desirable variants, the price should reflect a standard pressing.

Selling smart

Documenting runout markings transforms a general listing into a specialized, high-value item. The single most effective addition to a listing is a macro photograph of the dead wax on both sides, clearly showing the matrix numbers. Using specific terminology in the description—e.g., "Matrix: A-1/B-1, Early Pressing"—allows buyers to filter specifically for that variant, enabling the seller to command a premium over generic listings.
