How to Spot Valuable Antiques at Estate Sales

Tina

Flip it over

The bottom of a piece tells you more than the front. Maker's marks, patent numbers, country of origin. A bowl that says "Pyrex" on the bottom is worth $5. One that says "PYREX" in all caps with a specific pattern number might be worth $80.

Same with furniture. Pull out the drawers and look for dovetail joints, stamps, or labels. A dresser with hand-cut dovetails is probably pre-1900. Machine-cut dovetails are later but still solid. Staples and particleboard? Walk away.

Know the names

You don't have to be an expert, but recognizing a few brands goes a long way at Willamette Valley estate sales:

Furniture: Heywood-Wakefield, Drexel, Henredon, Ethan Allen (the older stuff). Pottery: Roseville, McCoy, Rookwood, Bauer. Glass: Blenko, Murano, Fenton. Kitchen: Griswold, Wagner, Le Creuset, vintage Pyrex.

If you see those names, take a closer look.

Weight tells you a lot

Heavy usually means quality. A heavy ceramic vase is probably stoneware, not dollar-store pottery. Heavy silverware might be sterling, not plate. Heavy furniture is solid wood, not veneer over particleboard.

Pick things up. You can feel the difference.

Check for repairs

Restored antiques are worth less than originals. Look for paint over paint, replaced hardware, refinished surfaces, and repaired cracks. None of these are deal-breakers for a piece you love, but they affect what you should pay.

The 30-second phone test

If something catches your eye and you're not sure, look up the maker's mark on your phone. eBay sold listings (not active listings, sold) tell you what people actually paid. Takes 30 seconds and can save you from overpaying or, better, help you spot a bargain the estate sale company underpriced.

Show up early

The best pieces go Friday morning. If you're serious about finding something good, check our upcoming sales and plan your route.
