Thank you for submitting your item for appraisal. This appears to be a late 19th century american cast brass etagere or plant stand, consisting of three identical round shelves and three legs, decorated in the italian renaissance revival style, with accanthus leaf, mascaron etc. A patent number search yielded no result unfortunately. The estimate is based on similar sold at auction. There is no measurement for the sentimental value you might attach to the item.
