Shellac Records and 78s: How to Identify, Handle, and Value Them
A shellac record is heavier than vinyl, thicker at the edge, and it shatters rather than bends. Most are 10-inch discs playing at 78 revolutions per minute. Our family has bought collections through Cash For Records since 2001. These discs turn up in almost every estate we visit. Sellers who want to sell vinyl records in Jacksonville, FL often find a stack of these underneath the albums. Pick one up before you do anything else, because the weight in your hand answers most of the questions.
Telling Shellac Apart From Vinyl
Weight gives it away immediately. A shellac disc feels dense for its size, closer to a dinner plate than a record. Vinyl of the same diameter feels light and gives slightly when you press the edge. Shellac does not give at all, which is the property that makes it dangerous to handle.
Sound is the next test, and it costs nothing. Tap the surface gently with a fingernail. Shellac returns a dull, flat knock with no ring to it. Vinyl answers with a faint hollow tone and a little sustain. Once you have heard both, you will never confuse them again.
Look at the groove under a bright light. Shellac records carry a wide, coarse groove you can see clearly without magnification. Vinyl uses a microgroove, which reads as fine lines rather than visible channels. That difference exists because the two formats were cut for different stylus sizes. It matters at playback time more than anything else here.
The surface finish tells you something too. Shellac tends toward a matte or slightly grainy look, since the material was mixed with mineral fillers and fibers rather than being pure resin. Vinyl is smoother and glossier, and it holds a deeper black. Hold both at an angle to a window, and the difference in reflection is obvious.
Sizes, Weight and Labels That Date a 78
Diameter narrows the era quickly. Most 78s are 10-inch discs, which was the standard for popular songs of three or four minutes a side. The 12-inch format carried longer classical works and some jazz sides. Smaller novelty and children’s discs exist as well, though they turn up rarely in the collections we see.
Label design does the heavier dating work. Company logos, typefaces, and address lines changed on a regular schedule. Those changes are documented well enough to place a record within a few years. Look for the company name, the catalog number, and any address printed around the rim. Deep groove rings and paste-on label variations also appear on some pressings and matter to collectors.
Here is how the two materials compare at a glance.
| Feature | Shellac 78 | Vinyl LP or 45 |
|---|---|---|
| Common size | 10 inch, some 12 inch | 12 inch, 10 inch, 7 inch |
| Speed | 78 RPM | 33⅓ or 45 RPM |
| Groove | Wide and visible | Microgroove, fine |
| Weight and feel | Heavy, rigid, no flex | Lighter, flexes slightly |
| Failure mode | Chips and shatters | Warps and scratches |
| Typical era | Through the late 1950s | 1948 onward |
Speed is worth checking rather than assuming. The industry settled near 78 revolutions per minute over time, and earlier discs ran at speeds that varied by maker. Many labels print the speed directly, which saves the guesswork. Anything marked 33 or 45 is vinyl regardless of how heavy it feels.
Why Shellac Breaks and How to Handle It
Shellac is a resin mixed with mineral filler, and the result behaves like a ceramic. It has almost no flex, so any force goes straight into a crack. A 78 dropped from waist height onto a tile floor usually breaks into several pieces. That single property drives every handling rule worth following.
Carry them one at a time, flat against your forearm or held by the edges with both hands. Never fan a stack the way you might flip through albums, since the discs knock against each other and chip at the rim. Edge chips are the most common damage we find, and they often start a crack that runs inward later. Keep them away from table corners and hard surfaces while you sort.
Temperature swings make brittle material more brittle. A box of 78s that spent a summer in a Florida garage is far more fragile than one kept indoors. Nothing has to look wrong for that to be true. Let a cold or hot box come back to room temperature before handling the contents. Cleaning deserves the same caution, because water and alcohol-based products can attack the surface and lift the label. Knowing what is safe matters before any cloth touches the disc, and the details on cleaning vintage 78 records spell out what to use and what to avoid.
Sleeves and Cleaning
Original sleeves are usually brittle paper and often in poor shape. Replace torn sleeves rather than forcing a disc through a split. Keep the old ones if they carry label artwork or a shop stamp. Those details sometimes matter to collectors as much as the record.
What Decides the Value of a 78
Value on a 78 comes down to the same factors that drive any record. Artist, genre, pressing, rarity, demand and condition set the number between them. Age by itself does nothing, which surprises people holding a disc from the 1920s. Plenty of 78s were pressed in enormous quantities and survive in volume today.
Genre does much of the work. Early blues, jazz and certain regional recordings draw steady collector interest, while mass-market popular titles from the same decades generally do not. Condition then decides where inside that range a disc lands. A clean copy of a scarce side is a different proposition from a chipped copy of a common one. Age does not level that out. Anyone wondering how age, genre, and condition add up to a price can find more in what old records are worth.
Condition on shellac is read differently from vinyl. Edge chips, hairline cracks, and heavy grey wear from steel needles are the things we look for. Surface noise rises as the groove wears, and a record played many times with a worn needle loses fidelity permanently. Labels matter too, since water damage and tears pull a disc down the scale.
We do not publish prices, and no honest buyer can quote one sight unseen. What we can do is explain how we reached a number once the records are in front of us. Sellers hear which discs carried the weight and why the rest did not.
Storing 78s So They Survive
Storage for 78s follows the same logic as vinyl, with less margin for error. Upright, snug and supported is the whole approach. The weight works against you, because a leaning 78 puts real load on the discs beside it.
Run through this before you put a box away.
- Store them upright, never stacked flat, since the weight below cracks the discs underneath
- Divide rows every six inches or so, because 78s are heavy enough to lean a whole section
- Keep boxes off concrete, where slab moisture reaches paper sleeves and labels
- Use conditioned indoor space, avoiding garages, attics and anything on an exterior wall
- Line the box with something soft, so no disc rests directly against a hard corner
Containers matter more here than with vinyl. A flimsy box that sags when lifted puts a bending load on rigid discs, which is how a whole row cracks at once. Use rigid crates or purpose-built boxes. Keep them light enough to carry comfortably, and never fill one past the point where you can lift it level. If a box has to move, empty half of it first.
Leave the stack where it is once you decide to sell. We would rather assess a collection in the place it has been sitting than have it carried across a house twice. Moving 78s is where most of the breakage happens, and breakage cannot be undone.

How We Grade 78s on a House Call
Grading happens where the records live, with the collection still in its box. Most of our Florida appointments run through Jacksonville, FL, and the Beaches. Our buyer works through the stack by hand, reading labels and checking each disc at an angle under a strong light. Chips, cracks, and label damage show up in that pass. Nothing gets rushed, because a 78 handled carelessly during grading is a 78 nobody can sell.
Play grading follows for anything promising. A turntable with the correct stylus goes on the record so our buyer can hear what the groove actually sounds like. Surface noise, needle wear, and skips all come through in a few seconds of listening. Each disc then gets a grade running from Mint down to Poor, with the disc and its sleeve scored separately.
The offer comes together at the end of the visit, and we explain how we arrived at it. Payment is cash on the spot for whatever fits what we buy. The records leave with us that day, packed by people who handle them every week. If you want to read around the subject first, a look at what these discs have been fetching is available in the 78 RPM records price guide.
Frequently Asked Questions About Shellac Records and 78s
These come up on most calls about 78s, usually from someone who inherited a box and has never handled one. The answers below cover identification and safety before anything else. Nothing here needs equipment beyond a bright light and a careful pair of hands.
How can I tell if a record is shellac or vinyl?
Weight and flex answer it fastest. Shellac feels dense and rigid with no give at the edge, while vinyl is lighter and flexes slightly. Tap the surface, and shellac returns a dull knock with no ring. The groove on a shellac 78 is also wide enough to see clearly without magnification.
Are all 78 RPM records made of shellac?
Most are, particularly anything pressed before the late 1950s. Some later 78s and reissues were pressed in vinyl, which is why the weight test matters more than the speed printed on the label. Vinyl 78s exist in smaller numbers and handle far better, since they flex rather than shatter.
Can I play 78s on a modern turntable?
Only with the right setup. A turntable needs a 78 speed setting and a stylus cut for the wider groove. A standard microgroove stylus rides the wrong part of the groove wall. Playing a 78 with the wrong stylus damages the record and produces poor sound. We bring suitable equipment to appointments.
Are old 78s valuable because they are old?
Age alone does not create value. Artist, genre, rarity, demand, and condition decide it, and many 78s were pressed in very large numbers. Early blues and jazz sides tend to hold collector interest, while mass-market popular titles from the same era usually do not. A clean scarce disc beats a chipped common one every time.
What should I do with a cracked or chipped 78?
Keep it with the rest and let a buyer look. A chip at the outer edge sometimes leaves the playable area untouched, while a crack running toward the label usually ends the record’s usefulness. Do not try to repair either one. Adhesives contaminate the groove and make a damaged disc harder to assess.
Get a Straight Read on the Box in Your Attic
Tell our team roughly how many 78s you have, which labels and artists appear most, and what condition the discs and sleeves are in. Mention the vinyl sitting alongside them as well, since most collections hold both. That description is usually enough for us to say whether a visit makes sense.
We buy jazz, blues, soul, R&B, rock, punk, and metal across 78s, LPs, 45s, and 12-inch singles. Country, big band, swing, and pop fall outside what we handle at the moment. Our buyer travels to you, grades everything in person, and pays cash on the spot for whatever fits.
