Old radios turn up in almost every estate we handle. They are tucked in closets, stacked on garage shelves or still proudly displayed in the living room. Most bring a modest price, but a few are worth far more than families expect. Here is how to tell what you have before it ends up in the donation pile.

What kind of radio do you have?

• Early battery sets (1920s). Long, boxy wooden cabinets with several dials across the front, from makers such as Atwater Kent and Crosley. Many needed separate batteries and a horn-style speaker.
• Cathedral and tombstone radios (1930s). The classic arched “cathedral” shape and the taller, squared-off “tombstone” tabletop sets in wood. Philco, Zenith, RCA and others made them in large numbers, so the exact model and condition matter a great deal.
• Console radios. Floor-standing furniture radios. Beautiful, but large and heavy, so most buyers are local.
• Bakelite and Catalin tabletop sets (late 1930s to 1940s). Small molded plastic radios. Brown or black Bakelite is common. Catalin is the jewel of the group, made in bright and sometimes marbled colors like red, green, butterscotch and blue.
• Transistor radios (1954 and later). Pocket and portable sets. The Regency TR-1, the first commercial transistor radio, reached stores on October 18, 1954 for $50. Colorful pocket radios from the 1950s and early 1960s are popular with collectors today.

Why Catalin gets collectors excited

Catalin cabinets were produced from the late 1930s into the late 1940s, and relatively few survived. Heat made them brittle, and years in hot attics, sheds and barns destroyed many more. That scarcity is why the best examples bring serious money at auction: a Fada “Bullet” has sold for up to about $6,000, and a near-perfect Emerson AU-190 tombstone reportedly brought about $25,000. Common Catalin sets sell for far less, and cracks, heavy discoloration and replaced parts lower the price quickly. Look-alikes made from other plastics are common too, so it pays to have an expert take a look.

What makes an old radio valuable

• Maker and model. Look for a label or stamped model number on the back, the bottom or inside the cabinet, then look it up on Radiomuseum.org.
• Rarity and design. Unusual styling, mirrored glass, chrome and bright colors draw more bidders than plain brown boxes.
• Condition and originality. Original knobs, back panel, dial glass and finish matter most. Cracks, missing knobs and amateur repairs lower value.
• Working or not. Many collectors happily buy non-working radios, because they plan to restore them anyway.

Please don’t plug it in

It is tempting to see whether an old tube radio still works, but a set that has sat for decades should not be plugged in until a qualified technician has checked it. Old capacitors break down with age, and powering up an unserviced radio can damage it or even start a fire. When we don’t know a radio’s condition we sell it as untested, and experienced buyers expect that.

Keep the original finish

Resist the urge to refinish. Stripping a lacquered wood cabinet, coating it in polyurethane or painting it lowers the value. A gentle dusting is all most radios need. Keep every piece together, including the back panel, knobs, tubes and any manuals or original boxes.

An Arizona tip: keep radios out of the heat

Garages and sheds here can get extremely hot in summer. Heat makes old plastics brittle and is hard on wooden cabinets and their finishes, so store radios indoors and out of direct sun.

Look for the rest of the collection

Where there is one radio, there are often more: shortwave portables like the Zenith Trans-Oceanic, spare tubes, old speakers, phonographs and ham radio equipment. Keep them together. Collections often sell better as a group of related lots.

Old concert shirts, faded souvenir tees and worn-in sports shirts are some of the hottest vintage clothing around. A real 1980s or early-1990s band tee can bring serious money, but reproductions are everywhere. These are the clues buyers check, and why no single clue is proof on its own.

1. Check the stitching on the sleeves and hem

Older tees usually have a single line of stitching on the sleeve and bottom hem. Double stitching became common from the mid-1990s on. Some transition-era shirts mix the two. Single stitch is a strong sign of age, but counterfeiters know it, so keep checking.

2. Read the tag

A sewn-in fabric tag points older. Tagless printed neck labels mostly arrived in the 2000s. Classic vintage blanks include Screen Stars, Hanes (including Beefy-T), Fruit of the Loom, Russell, Champion, Stedman, Velva Sheen and All Sport. “Made in USA” is common on 1980s and 1990s shirts. Production moved overseas mostly after 2000.

3. Feel the fabric and look at the fit

1980s tees tend to be thin, soft and a little longer. 1990s tees are boxier and heavier with wider collars. Decades of washing leave cotton soft, thin and unevenly faded in a way that is hard to fake.

4. Study the print

Older screen prints often crack naturally with wear. Puff, flocked and iron-on transfer prints also help date a shirt. Modern digital prints tend to look smooth and flat. Distressing that looks too even is a warning sign.

5. Find the copyright date

A small © year near the graphic tells you when the artwork was created, so it is the earliest the shirt could be. A shirt marked 1997 cannot be from 1992, but it could have been printed later.

Put the clues together

The stitching, tag, fabric, print, country of origin and copyright date should all point to the same era. When they disagree, be skeptical.

What sells best

Band and tour shirts, especially from the 1970s through the 1990s, lead the market. Harley-Davidson dealer tees, old sports and college shirts, and quirky local souvenirs, including plenty of Route 66 and Arizona tourist tees, are strong too. Wash vintage tees in cold water and hang them to dry.

Records are back in a big way. In 2025, U.S. vinyl sales grew for the 19th year in a row and passed $1 billion for the first time since 1983, according to the Recording Industry Association of America. That means the crates of LPs in the garage or hall closet deserve a careful look before they go anywhere.

What makes a record valuable

• Demand for the artist and album. Classic rock, jazz, soul, punk and early hip-hop are steady sellers. Common easy-listening albums usually are not.
• Which pressing it is. An original first pressing is often worth much more than a later reissue of the same album.
• Condition. This matters most. A scratched copy of a rare album can be worth less than a clean copy of a common one.
• Everything that came with it. Original inner sleeves, posters, lyric sheets and stickers all add value. Promotional “white label” copies can be especially collectible.

How to identify the pressing

Look at the smooth band between the last song and the label, called the “dead wax” or runout. Etched letters and numbers there identify where and when a record was pressed. Type the album name and those numbers into Discogs, the large record database, to find the exact version and see recent sale prices for it.

How records are graded

Buyers use a standard scale, from best to worst: Mint, Near Mint, Very Good Plus, Very Good, Good, and Poor. Hold the record under a bright light. Light scuffs that do not affect play are acceptable for Very Good Plus. Deep scratches, warps and heavy wear drop the grade quickly.

An Arizona warning: heat warps vinyl

Never store records in a garage, shed or car here. Summer heat can warp a record in an afternoon. Keep them indoors, standing upright like books, in their sleeves and out of direct sun.

Don’t forget the gear

Vintage turntables, receivers and speakers from brands like Marantz, McIntosh, Technics and Pioneer are in high demand right now, even when they need service.

Vintage Pyrex is one of the most-searched kitchen collectibles in America, and it turns up in nearly every Arizona estate we sell. Most pieces are worth a modest amount, but a few patterns regularly bring hundreds of dollars. Before you donate that stack of mixing bowls, check them against this list.

8 patterns collectors pay up for

Prices below are recent sales compiled by Hunker. Real prices vary with condition and demand.

1. Pink Butterprint (1960). Offered through a trading-stamp program and the rarest of the Butterprint colors. A set of three Cinderella casseroles with lids has sold for $800 to $1,250. Turquoise Butterprint is far more common.
2. Pumpkin Butterprint (1965). Also a stamp-book premium with no regular production run. Three bowls recently sold for over $1,000.
3. Atomic Eyes chip and dip (1950s). Two bowls joined by a metal bracket. Some pieces have no Pyrex backstamp. Complete sets have sold for nearly $600.
4. Balloons chip and dip (1958). A promotional set. Complete and unused in its original box, one sold for $575.
5. New Dots mixing bowls (1969). Orange, yellow and blue, plus a green 4-quart bowl added later. A full set of four has sold for over $400.
6. Colonial Mist, all blue (1983 to 1986). The last opalware Pyrex pattern. Most sets alternate blue and white, so an all-blue set is the prize, at about $400.
7. Pink Gooseberry refrigerator set (1956). Four dishes with lids. A set sold for $375. The lids matter.
8. Friendship (early 1970s). Red birds on white. Mixing bowl sets have brought about $300.

How to tell what you have

• Flip it over. Most pieces carry a Pyrex backstamp and a size or model number that helps match the pattern.
• Count the set. Complete nesting sets, with every size and the original lids, are worth far more than single bowls.
• Check the shine. Dishwashers dull the painted finish. Collectors call this “DWD” (dishwasher damage), and it lowers value. Hand-wash vintage Pyrex.
• Keep the extras. Original boxes, brackets, carafes and lids can double a price.

The easy rule

Bright, glossy colors, complete sets and unusual patterns are the ones to set aside. Faded, scratched singles are still fun to cook with, and buyers at auction love them too.

Pink plates in Grandma’s china cabinet. A green candy dish that looks almost neon. A yellow vase that seems to glow on a sunny windowsill. These are some of the most common treasures we find in Arizona estates, and they are often mixed up with each other. Here is how to tell Depression glass, uranium glass and Vaseline glass apart in a few minutes, with one inexpensive tool.

Depression glass: the colorful everyday glass of the 1920s and 1930s

Depression glass was mass-produced during the Great Depression, mostly in the 1920s and 1930s, and was cheap enough to be handed out as a store or movie-theater giveaway. The classic colors are pink, green, amber and blue, plus clear. Many pieces carry named patterns, so a plate is often part of a larger set.

• Look for small flaws. Mold seams, tiny bubbles and slight unevenness are normal. They were made fast and inexpensively.
• Check the pattern. Popular patterns have been reproduced. Compare your piece with a pattern guide; reproductions often have blurrier details or slightly “off” colors.
• Look underneath. Real age usually shows as fine scratches and a wear ring on the base where it sat on shelves for decades.

Uranium glass: the piece that glows

Uranium glass contains a small amount of uranium oxide, which gives it a yellow-to-green color. Under ultraviolet light it glows a bright, unmistakable green. It was especially popular in the late 1800s and early 1900s.

Vaseline glass is a type of uranium glass with a pale yellow-green, slightly oily look. That is where the name comes from. In short, Vaseline glass is usually uranium glass, but not all uranium glass is Vaseline glass.

The one tool you need: a UV flashlight

A small UV (blacklight) flashlight costs about ten dollars and settles most questions in seconds. Take it into a dark room and shine it on the glass:

• Bright green glow: uranium glass, including Vaseline glass and some green Depression glass.
• No glow: most pink, amber, blue and clear Depression glass.

That overlap matters. A green Depression-era dish can contain uranium, so the UV test is the only easy way to tell.

Is uranium glass safe?

The amount of uranium is small, and collectors generally treat it as safe to own and display. If you are unsure, use it as a decorative piece rather than for food.

What makes it valuable?

Pattern, color, rarity and condition drive price. Single common pieces are usually modest. Complete sets, rare colors and pieces with no chips sell best. Run a fingertip gently around every rim to feel for chips before you price anything.
