Hi Marie,

Thank you for contacting Mearto with your appraisal inquiry.
This clock was one of literally thousands made in Europe and England in the mid and late 19th Century; sadly, supply far outweighs demand and these tend to sell - when offered at auction - for between $50-125, with working clocks more likely to bring the higher value. I've valued this at $75-125 as it's a nice example but would be very surprised if it were to bring more.
Based on the photos and information provided, and subject to examination, this is:

A Victorian parcel gilt onyx mantel clock
unattributed maker, probably English, mid-late 19th Century
Of rectangular section, with peaked cornice over an entablature decorated with cherubs, over a cast brass dial with Arabic chapter rings, flanked by engaged columns, on a box base; incised gilt decoration throughout. The back later engraved "119 280"
Height: 10-3/4 inches; width 15-3/4 inches; depth 5-3/4 inches.
CONDITION: Working condition not verified; this clock appears to have no cosmetic defects other than minor age commensurate to age and use.
PROVENANCE: Inherited
$75-125*
*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.
