Hi Deborah

Thank you for contacting Mearto with your appraisal inquiry.

I wasn't familiar with the firm Karcher & Rehn and an internet search suggests it was an obscure firm or short-lived partnership. They might also be the retailers and not the makers of this table.

From the style and construction, I can tell you that this is comparable to pieces made in the 1920 and 1930s, suggesting a likely date of origin; this seems to track with your family's history of the table.

The market is heavily populated with such tables - of this vintage and otherwise - and when they come to auction, they bring fair-market (akin to wholesale) prices between $600 and $900.

Based on the photos and information provided, and subject to examination, this is:

A near antique Colonial Revival style walnut expanding dining table
labeled Karcher & Rehn, Philadelphia, circa 1920-30s
Of rectangular form with rounded ends, raised on tall cabriole legs terminating in ball-and-claw feet.
Height: 30 inches; in closed form, it is 44 inches wide and 62 inches long. With two leaves.
CONDITION: This table appears to be in generally good condition with wear commensurate to age and use.
PROVENANCE: Inherited
$600-900*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
