Good afternoon, Lucy,
Thank you for submitting photographs to Mearto for appraisal. You have a 20th Century Renaissance revival style marble-top dresser with mirror. Almost certainly manufactured on a large scale. Condition seems fairly good and these are useful, though not in too much demand these days. If there was a maker's name, brand or label to further identify who made it, the value might be adjusted a bit but, without it, it is worth $200-300.
Please let us know if you have any additional questions.
Many thanks again.
