Hello, this item is a Southeast Asian Dong Son-style bronze rain drum top, gong, or decorative wall plaque, likely Vietnamese or Thai/Burmese inspired, probably late 20th to early 21st century. The circular bronze form has concentric cast geometric bands, a central raised star or sunburst motif, and an aged dark patina with surface rubbing and oxidation. The form relates visually to traditional Southeast Asian bronze rain drums, but the photographs do not show a full drum body, side handles, frog figures, or strong evidence of archaeological age, so it should be described as a decorative or revival piece rather than an ancient Dong Son drum.

The piece appears to measure approximately 62 cm in diameter, which gives it good decorative scale, but the shallow profile and wall-hanging arrangement suggest it was made for display rather than ritual or musical use. Condition appears fair to good, with scratches, patina wear, surface deposits, and small irregularities consistent with decorative age and handling. Modern bronze rain drum and Dong Son-style decorative pieces have an active market, but incomplete or plaque-like examples bring far less than full antique drums. Based on the form, size, likely modern date, condition, and lack of provenance, the fair market value is $150 - $350 USD.
