Hello, this item is a painted portrait of a woman executed in a 19th century academic style, most likely mid to late 19th century in inspiration. The sitter wears a lace head covering, dark dress with a wide neckline, and a gold tone brooch and necklace typical of European bourgeois portraiture of that period. However, the surface appearance, uniform smoothness of the paint layer, and the slightly muted photographic quality of the image suggest this may not be a hand painted 19th century oil, but rather a later painted reproduction or a photo based image on a metal support. The description indicating painting on metal and origin from the former Soviet Union strongly suggests a 20th century decorative reproduction, as many such portraits were reproduced on metal plates during the mid 20th century for domestic decoration.

Decorative 20th century reproductions or unsigned portraits on metal typically trade between 100 USD and 400 USD in the secondary market. Based on the visible characteristics, lack of signature, and likely 20th century production, a realistic current market value would fall in the range of 150 USD to 350 USD.
