Hello, this item is a large cast metal statue depicting Green Tara in a Tibetan Buddhist style, most likely produced in the late 20th century rather than the 19th century. The proportions, casting seams, relatively soft detailing, and the surface patina visible on the base are consistent with modern decorative export bronzes made in Nepal, India, or Tibet for the international market from approximately the 1970s onward. Authentic 19th century Tibetan bronzes typically show finer chasing work, mercury gilding remnants, sealed bases with consecration cavities, and more complex alloy surfaces, none of which are clearly present here. The open hollow base and the uniform artificial oxidation further support a modern workshop production rather than a period ritual object.

From a market standpoint, large decorative Green Tara statues of this type and size, around 2.5 to 3 feet tall, usually sell based on decorative appeal and scale rather than religious or historical importance. Comparable modern cast examples typically trade between $300 and $900 USD in the current secondary market, with higher prices only achieved when there is confirmed age, documented provenance, or high quality gilding. Given the visible wear, outdoor exposure patina, and lack of indicators of early manufacture, a realistic current market value for this piece would fall in the range of approximately $400 to $700 USD.
