Hi Aconite,

Thank you for contacting Mearto with your appraisal inquiry.
Dower chests of the late 17th Century would have had straight feet instead of bracket feet (that was an 18th Century invention), so I'm inclined to think the legs and the casters are replacements.
Based on the photos and information provided, and subject to examination, this is:

A Cromwellian or Jacobean era carved oak coffer
English, third quarter 17th Century
Of rectangular section with three-field paneled lid and front, with double-paneled sides, on bracket feet. With stylized foliate decoration. Dated 1672
33 inches tall, 52-1/2 inches wide, 25-1/2 inches deep
CONDITION: With later casters
PROVENANCE: Inherited
$400-600*
*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.
