Determining the Provenance-Useful Tips!

To a marketing executive, a “Maker’s Mark” is the original logo. To an antique curator, it’s the DNA of an asset. Finding a signature doesn’t just prove who made it; it provides the provenance that allows a piece to appreciate.

1. The “Brown Furniture” Hunt (19th Century)

Authentic Georgian or Victorian pieces rarely have flashy logos. You have to look for “The Ghost of the Maker.”

• Where to look: The secondary wood. Pull out a drawer and look at the sides and bottom. If it’s high-quality mahogany on the outside but cheap, rough-cut oak or pine on the inside, you’ve found an authentic period piece.
• The Mark: Look for impressed stamps (names hammered into the wood) on the top edge of drawer fronts or back panels.
• The “Repro” Red Flag: Perfectly uniform, machine-cut dovetail joints. Authentic 19th-century joints will be slightly irregular because they were cut by a human with a saw, not a CNC machine.

2. Art Deco & Murano Glass

Glass is notoriously tricky because “Murano” is a location, not a brand.

• The Pontil Mark: Flip the vase over. You should see a “scar” or a slightly rough, ground-down circle where the glassblower broke the piece off the rod. If the bottom is perfectly smooth and molded, it’s a factory-made fake.
• The Signature: High-end masters like Venini or Seguso often etched their names into the glass with a diamond-point pen. It’s faint—you’ll need your phone’s flashlight to catch the light on the etching.
• The Label: Look for the Vetro Artistico® Murano holographic sticker. In 2026, many authentic pieces also come with a digital NFT certificate of origin.

3. Studio Pottery (The “Art” Play)

Studio pottery is all about the Cypher.

• The Mark: Most potters use a monogram (like an “LR” for Lucie Rie). These are usually incised (carved into the wet clay) or impressed with a small seal.
• The “Search” Strategy: If you see a weird symbol that looks like a fish or a bridge, don’t guess. Use a “Pottery Mark Lexicon” or a reverse image search. A single rare mark can turn a $50 thrift store find into a $5,000 auction lot.

4. Mid-Century & 90s Tech

• The “Paper Trail”: For MCM (Herman Miller, Knoll), look for paper labels or foil stickers under the seat. If the sticker is missing, look for a “shadow”—a rectangular patch where the wood is a different color because the sticker protected it from 60 years of light.
• 90s Tech: For “New Antiques” like early Apple products or Sony Walkmans, the “mark” is the Serial Number. In the 2026 market, collectors use these to verify the “Production Week.” An “early-run” unit (Week 1-5) is worth 3x more than a late-run unit.

The Executive’s “Pocket Toolkit”

When you go scouting, bring these three things:

1. A High-Lumen Flashlight: To see faint glass etchings and dark drawer interiors.
2. A Magnifying Loupe: To check if a “signature” was printed (fake) or hand-carved (real).
3. Your Phone: To cross-reference marks on databases like Marks4Antiques or Artnet.
