How to Spot Authentic RPM Record Pressings and Keep Them Safe for Decades

If you’ve ever held a dusty box of old vinyl and wondered “Is this the real deal?” you’re not alone. At Vinyl RPM Vault we get that question a lot, especially when a new “rare” pressing shows up on a marketplace. Knowing how to tell a genuine RPM record from a copy can save you money, time, and a lot of heartache. Below I’ll walk you through a few easy steps to spot the real thing and then share simple ways to keep it looking good for years.

The First Clues: Look at the Sleeve

1. Check the label and catalog number

RPM Records always printed a small catalog number in the lower right corner of the sleeve. It’s usually a three‑digit code like “RPM‑207.” If you can’t find it, or the font looks off, that’s a red flag. At Vinyl RPM Vault we keep a quick cheat sheet of the most common numbers for each era, so you can compare in a flash.

2. Feel the paper

Original sleeves were printed on a slightly heavier, matte paper. Knock‑off prints often feel too glossy or too thin. Run your fingers over the corners; the real thing has a faint texture you can feel.

3. Spot the tiny details

RPM loved adding little things like a stamped “Made in USA” or a tiny star logo near the bottom. These marks are usually missing on fakes. If you see a big, bold logo that looks like it was added later, that’s a clue it’s not authentic.

The Record Itself: What to Examine

1. Look at the run‑out groove

The run‑out groove is the blank space near the label where the needle lifts off. Authentic RPM pressings have a faint etched code—usually a combination of letters and numbers. It might read “R‑A1” or “M‑B2.” If the groove is smooth or has a printed label instead of an etching, you’re probably looking at a copy.

2. Check the weight

Most RPM pressings from the 1970s onward weigh about 120‑140 grams. If the record feels unusually light (under 100 g) or oddly heavy (over 180 g), it could be a re‑press or a counterfeit. At Vinyl RPM Vault we keep a small scale on the desk for quick checks.

3. Listen for the “pressing sound”

Put the needle on a quiet track and listen for a faint “click‑click” as the stylus passes the inner groove. Real pressings have a clean, consistent sound. If you hear extra rumble or a metallic scrape, the vinyl might be a cheap copy.

Provenance: The Story Behind the Record

1. Ask for a receipt or proof of purchase

If the seller can show a receipt from a reputable shop or an original store tag, that adds credibility. At Vinyl RPM Vault we always ask for a photo of the original receipt when we buy a new addition for the collection.

2. Look for the original packaging

Original RPM records often came with a cardboard inner sleeve or a paper insert with liner notes. If the record is missing these, it doesn’t mean it’s fake, but it does mean you need to be extra careful.

3. Trust your gut

Sometimes a seller’s attitude says a lot. If they’re vague about details or avoid answering specific questions, that’s a warning sign. At Vinyl RPM Vault we’ve learned to trust our instincts after years of dealing with collectors.

Simple Preservation Tips: Keep Your RPM Gems Safe

1. Store upright, not flat

Lay the records on their edges in a sturdy shelf. Stacking them flat can cause warping over time. Vinyl RPM Vault’s own storage unit is just a set of metal racks with a little rubber padding on each shelf.

2. Keep them cool and dry

Heat and humidity are the biggest enemies of vinyl. Aim for a room temperature of about 68 °F (20 °C) and keep the humidity below 50 %. A simple digital hygrometer can help you monitor the conditions.

3. Use proper inner sleeves

Never leave a record in its paper sleeve for long periods. Slip it into a high‑density polyethylene (HDPE) inner sleeve. These are cheap, clear, and protect the record from dust and static. Vinyl RPM Vault always swaps out the old paper sleeves when we add a new record to the vault.

4. Clean before you play

A quick brush with a carbon‑fiber brush before each play removes surface dust. For deeper cleaning, a gentle solution of distilled water and a few drops of isopropyl alcohol works well. Just be sure not to soak the record—wipe it dry right away.

5. Handle by the edges

Never touch the playing surface. Finger oils can cause permanent damage. Hold the record by the edges or the label, just like you’d hold a photograph.

A Little Story from Vinyl RPM Vault

Last month I got a call from a friend who found a “rare” RPM pressing of a 1974 soul album at a garage sale. The sleeve looked a bit off, but the price was too good to pass up. I asked her to send a photo of the run‑out groove. The etching read “R‑C3,” which matched our catalog for that release. We bought it, cleaned it, and now it sits proudly on the top shelf of Vinyl RPM Vault. The whole experience reminded me that a little patience and a few simple checks can turn a mystery into a treasure.
