Question 1

How do I identify genuine mid-century modern furniture versus reproductions?

Accepted Answer

Authentic mid-century pieces from 1945 to 1969 show specific construction techniques: solid wood joints rather than MDF, original upholstery foam that has yellowed and compressed, and manufacturer labels from companies like Herman Miller, Knoll, or Fritz Hansen. Check underneath for date stamps. Reproductions often use Phillips-head screws (uncommon in originals before 1960), have uniformly colored wood without natural aging, and lack the subtle warping from decades of use. For Danish pieces, look for the burned-in maker's mark on the underside.

Question 2

What are the most undervalued periods in furniture collecting right now?

Accepted Answer

As of early 2026, English Edwardian furniture (1901 to 1910) remains dramatically undervalued compared to Georgian or Victorian equivalents, often selling for 20 to 40 percent of 1990s prices. Postmodern Italian furniture from the 1980s Memphis group, which peaked around 2019, has cooled to more accessible levels. Early American colonial furniture outside of museum-quality examples has also softened significantly. American Arts and Crafts pieces by lesser-known makers beyond Stickley continue to offer strong value relative to their quality and age.

Question 3

Does refinishing antique furniture destroy its value?

Accepted Answer

In most cases, yes. A mahogany chest with its original shellac finish, even if cloudy or scratched, typically sells for two to four times more than an identical piece that has been stripped and re-stained. The exception is utilitarian pieces like farmhouse tables or industrial furniture, where a clean restoration can actually increase market value. For high-end pieces by known makers, conservators recommend cleaning and waxing only. If you must address damage, seek a conservator who can do reversible treatments rather than a furniture refinisher who will strip everything.

Question 4

How do Tiffany lamps get authenticated, and what do they sell for in 2026?

Accepted Answer

Tiffany Studios lamps are authenticated through a combination of base and shade markings, glass quality, and construction methods. Genuine shades use copper foil construction (not lead came), and the glass shows color variation when backlit. The Tiffany Studios stamp appears on both base and shade. Market values in 2026 range from around 4,000 dollars for simple Favrile glass table lamps to over 3 million dollars for exceptional Dragonfly, Wisteria, or Pond Lily examples. The record auction price remains the 2018 Christie's sale of a Pond Lily lamp at 3.37 million dollars.

Question 5

What should I look for when buying vintage Scandinavian furniture?

Accepted Answer

Start with the wood species: genuine Danish modern uses teak, rosewood (now CITES-restricted for post-1992 pieces), oak, or beech. Check for the manufacturer's label, typically a paper or foil sticker on the underside. Key makers include Carl Hansen (Wegner designs), Fritz Hansen (Jacobsen designs), and France & Son (Finn Juhl). Joints should be doweled or finger-jointed, not stapled. Original cord or leather on seats will show even wear patterns. Watch for replaced cord on Wegner Wishbone chairs, which is common but reduces value by about 15 to 25 percent.

Question 6

Are Art Deco chandeliers a good investment?

Accepted Answer

Art Deco lighting has appreciated steadily since 2015, with Lalique glass fixtures seeing particular demand. A genuine Lalique ceiling bowl from the 1920s sold at auction in late 2025 for over 35,000 euros, compared to around 18,000 euros for a comparable piece in 2018. Muller Frères and Degué fixtures have followed a similar trajectory. The key factors are signature presence, glass condition (no chips or repairs), and completeness of original hardware. Mass-produced Art Deco-style fixtures from the 1930s remain affordable at 500 to 2,000 dollars and offer strong decorative appeal.
