That's a nice patina on that piece of furniture. Looks like it is an early 19th century walnut or mahogany piece. Or is it a reproduction ? Many antiques dealers are very clever at making new furniture look old. Chains, coffee stains, bashing an old bit of wood around, smoke rooms, false papers etc.
Nah, it's repro. Look to the right. You can see the plywood in the box there.
