Engraved Octagonal Claw-foot table

My father was given this as a gift about 50 years ago so I know very little about its origins. All I can tell you is that it is a beautifully carved octagonal table with no visible markings of any kind underneath other than a black marker that says: 2455/63. I would like to find out the age of this table, who may have made it, and with today's value if at all possible.
