Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
In order to appraise these, I'd need an overall photograph, and a close-up of the detail you mention.
Photo upload instructions are here:
This is an American Victorian parlor set in the Eastlake style.
Ears of corn as a carving motif came into popularity with the Federal style, around 1800, but this set would date to the later 19th century.
Is this a settee and two chairs? Or some other configuration?
I'm happy to provide a value as well, if you let me know which pieces of furniture you have.
