AI Item Analysis

This is a white ceramic or porcelain dinner plate, viewed from the underside, resting on a textured woven surface. The physical characteristics include a classic round dinner plate shape with a smooth, glossy white glaze and a subtly scalloped or shaped rim edge. The underside reveals a prominent foot ring enclosing the central base. There are several visible markings printed and impressed on the base. A prominent red printed mark in the center reads verbatim: 'Gilman Collamore & Co. 5th Ave. & 30th STREET, NEW YORK.' Near the top edge of the inner foot ring, a faint green printed mark reads 'COPELANDS CHINA ENGLAND'. Additionally, there are hand-painted or stamped red numbers and letters near the bottom edge of the foot ring, including '3504B' and other small digits, alongside an impressed letter 'B' and a small red painted symbol resembling a cross or star. The overall condition appears clean with a glossy finish, though minor surface wear consistent with age and handling may be present upon closer inspection. The style is consistent with fine import porcelain retail dinnerware from the late 19th or early 20th century. The attribution in the name rests directly on the legible printed maker and retailer marks visible on the underside of the piece, though the item remains unauthenticated.

AI Appraisal Report

Based on what I can see in the photograph, this white porcelain dinner plate bears markings consistent with Copeland's China and the retailer Gilman Collamore & Co. of New York, suggesting a late 19th- or early 20th-century import piece. The underside displays a clear red retailer mark, a green Copeland's mark, and various pattern or inventory numbers. I cannot verify from a photo alone whether these marks are entirely correct for the period or if the piece is a later reproduction, copy, or replica. Physical inspection by a qualified specialist would be needed to examine the glaze chemistry, paste consistency, and wear patterns. Assuming the attribution is correct and the piece dates to the retailer's active period, fine porcelain tablewares of this type generally trade in a modest range depending on condition and completeness of a service. A single decorative plate in good overall condition with typical minor handling wear usually commands a modest collector interest, with estimated values often falling in the $100 to $200 range. If the item were determined to be a later decorative reproduction or in the style of the historic maker rather than a period piece, its value would drop significantly, likely to under $30. To establish greater certainty, an in-person examination, hallmark verification, and comparison against known examples would be required.
