Thank you for submitting your item for appraisal. This appears to be a mid 20th century persian tinned copper pitcher. The local craftsmen tend to use the rather easy to incise copper. Bronze, a very hard alloy of copper and pewter, would be very unlikely. Such jugs are quite common and are still being made in rural arears to be sold to tourists. The estimate is based on similar sold or offered at auctions. "Asking prices" in the trade can be higher and vary.
