8 Antiques That Go For Big Money – Plus 5 That Could Be Hidden Goldmines

That forgotten piece tucked away in a corner or passed down through generations might be worth far more than you think. In the ever-evolving world of antiques, some items are instantly recognizable as valuable, while others quietly appreciate in worth, unnoticed by most.

Whether inherited or stumbled upon at a flea market, the right antique can turn out to be a serious payday – if you know what to look for.

1. Early American Quilts

Handstitched stories of American history, these textile treasures can command prices from $5,000 to over $100,000. Pre-1850 examples with documented provenance are especially valuable.

Collectors prize unusual patterns, fine workmanship, and historical significance. Baltimore album quilts and those made by Amish communities rank among the most sought-after, representing both artistic achievement and cultural heritage.

2. Tiffany Lamps

Genuine Tiffany Studios lamps represent the pinnacle of Art Nouveau craftsmanship. Created between 1890-1930, these stained glass masterpieces regularly fetch six-figure sums at auction.

The most valuable feature intricate floral or dragonfly motifs. Their value comes from Louis Comfort Tiffany’s innovative glass techniques, creating luminous colors that still dazzle collectors more than a century later.

3. 19th Century Oil Paintings

Landscapes, portraits, and maritime scenes from this golden age of painting continue to appreciate. Works by recognized artists like Thomas Cole or Winslow Homer can sell for millions.

Even lesser-known artists’ works command respectable sums if well-executed. The key factors affecting value include subject matter, condition, provenance, and the artist’s reputation in the current market.

4. Sterling Silver Flatware Sets

Complete sets of sterling silver cutlery from renowned makers like Gorham and Reed & Barton command premium prices. Patterns like Francis I or Repousse are particularly desirable.

Surprisingly, many families have these treasures tucked away in dining room cabinets. A complete service for 12 with serving pieces in a sought-after pattern can bring $5,000-$20,000, depending on condition and rarity.

5. Rare Books And First Editions

First editions of beloved classics with intact dust jackets can be worth small fortunes. A first printing of The Great Gatsby with dust jacket sold for $377,000 in 2014. Condition is paramount in this collecting category.

Signatures, inscriptions, and association copies (books owned by famous individuals) can multiply value exponentially. Even relatively modern first editions like Harry Potter can fetch impressive sums.

6. Antique Persian Rugs

Hand-knotted masterpieces from the 19th century represent the height of textile artistry. Rare examples from Tabriz, Heriz, and Kerman regularly sell for tens of thousands.

The most valuable combine natural dyes, fine wool, intricate patterns, and historical significance. Collectors particularly prize rugs with unusual designs or colors, and those with documented provenance connecting them to notable collections or historical events.

7. Mid-Century Modern Furniture

Danish teak credenzas and Eames chairs aren’t just stylish – they’re investment pieces that continue to climb in value. Original pieces from designers like Herman Miller and Knoll can sell for thousands.

The clean lines and functional beauty of these 1950s-1960s pieces make them eternally desirable. Even mass-produced items from this era can command impressive prices if in good condition.

8. Art Deco Jewelry

Geometric brilliance defines these 1920s-1930s treasures. Pieces from prestigious houses like Cartier and Van Cleef & Arpels command astronomical prices at auction.

The combination of platinum, diamonds, and colored gemstones in bold, architectural designs makes Art Deco jewelry perpetually fashionable. Even unsigned pieces with quality craftsmanship and materials can be worth thousands to the right collector.

9. Turn-Of-The-Century Postcards

These unassuming paper treasures can be surprisingly valuable. Rare examples showing historical events, early aviation, or small-town America regularly sell for hundreds or even thousands.

Halloween and Christmas themed cards are particularly collectible. The most valuable postcards combine rarity, excellent condition, and compelling subject matter – especially those depicting vanished landmarks, early advertising, or cultural events.

10. Vintage Advertising Signs

Colorful remnants of commercial history, these eye-catching pieces command surprising prices. Porcelain signs for iconic brands like Coca-Cola or automotive companies can fetch five figures when in pristine condition.

Gas station memorabilia is particularly hot in the market. The appeal comes from their graphic design, nostalgic value, and increasing rarity – many were simply discarded when businesses closed or rebranded.

11. Old Typewriters And Mechanical Devices

Mechanical marvels from the pre-digital age are finding new admirers and rising values. Rare models like the Malling-Hansen Writing Ball or early Sholes & Glidden typewriters can command $10,000+. Even more common vintage Underwoods and Remingtons are appreciating steadily.

The tactile appeal, mechanical ingenuity, and connection to literary history make these devices increasingly collectible as technology continues its relentless march forward.

12. Pre-War Board Games And Toys

Childhood playthings from before 1945 can be serious collector items today. Original Monopoly sets from the 1930s, early Lionel trains, and pre-war teddy bears regularly sell for thousands. Condition and completeness are crucial factors in value.

The most sought-after items combine nostalgic appeal with historical significance, often reflecting the cultural or social climate of their era through graphics, themes, and materials.

13. Forgotten Studio Pottery

Handcrafted ceramics by notable 20th century artists can be hidden treasures. Works by masters like George Ohr, Lucie Rie, or Shoji Hamada command thousands, sometimes appearing at estate sales for a fraction of their worth.

The key is identifying maker’s marks and distinctive styles. Even lesser-known regional potters from the American studio pottery movement can have significant value to collectors focused on particular regions or aesthetic movements.
