Vinyl test pressing & promo auctions: acetates, searched at once

A genuine test pressing or acetate, often made in single-digit quantities to check a master before commercial release, is among the rarest formats any collector can own, and artist, era, and documented provenance drive value far more than the condition of an ordinary commercial copy would.

Why the right test pressing is easy to miss

Test pressings and acetates get listed by individual sellers across different platforms with no consistent naming, so a genuinely rare, single-digit-quantity pressing could appear anywhere, at any time, with no warning.

One search across every platform

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. A search for "test pressing," an artist, or "acetate" returns matching lots across all of them, with images, prices, and provenance details shown, sorted by platform in tabs.

Real results for "vinyl test pressing promo rare": a genuine "David Gilmour RARE ACETATE TEST PRESSING PROMO VINYL Pink Floyd Live At Pompeii" listing, found in one search.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: catch a genuine acetate before it's gone

Genuinely rare, single-digit-quantity test pressings sell within hours of listing, so save a search (an artist, "test pressing," or "acetate" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching vinyl lots before adding the rest of the platforms via the extension.

Built for how record collectors actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and VAT included) is always in front of you.
