Garrison dinning table

Was left this 15 years ago by great aunt. Was in immaculate condition but I was young and dumb ...there were 6 beautiful chairs 2 having arm rest... now we have 2 chairs that survived my children...one In good shape another One missing the wicker the table Is still in beautiful shape has to leaves that go into it to make it bigger ...underneath is where the carvings and the stamp that says Garrison.... just kind of wondering around what year this was made ...I can't find info AND what it could be Worth now thank you.
