I don’t know enough about furniture value to help you. I do know provable provenance can add a lot of value. Such markings can sometimes be found on drawer bottoms or under the top, visible when drawers are removed. Without a known maker, a known year, etc the price is usually driven by “the eye of the beholder”.
If the unit is solid (not wobbly), the drawers fit and function properly and there is no unseen damage, I could imagine it bringing $400+. If it can be accredited, considerably more. Again this is a novice opinion. A furniture dealer/restorer would be better versed to help you. Best wishes!
