You might check the Antiquie Roadshow website. It would depend on the wood, where it was made and who made it. Signatures? wear? replacements? Original finish? and then again if it over a certain amount, you will need to get it certified by a appraiser. You would need your tax person's help on what forms/documents you will need. Or go on the IRS website. Hope this helps and we cannot and should not give you any certain amount.

1920s to 1930s "Jacobean revival" style. Probably veneers and solids.

Worth depends entirely on the market in your town. Check craigslist to see what's the usual.

I'd price it at 50-75% of what a dresser and nightstand from a place like Ashley sells for.
