Oversized Decorative Yongle Tongbao Chinese Cash Coin

This is a large-scale decorative cast brass or bronze plaque modeled after a 15th-century Ming Dynasty 'Yongle Tongbao' cash coin. The piece is circular with a characteristic square hole at the center, resting on a contemporary black display stand. The face of the item features four raised Chinese characters: '永' (Yǒng), '樂' (Lè), '通' (Tōng), and '寶' (Bǎo), referencing the Yongle Emperor's reign (1402–1424). Physically, it exhibits a textured, sand-cast appearance with a significant aged patina consisting of dark oxidation and surface spotting, contrasted by the lighter, rubbed highlights on the raised lettering and outer rim. The construction is heavy and metallic, likely composed of an alloy intended to mimic an antique finish. Condition-wise, it shows minor pitting, irregular surface wear consistent with a decorative reproduction, and some discoloration that suggests it may be a late 20th-century or modern commemorative piece rather than a period artifact. The large size distinguishes it as a decorative wall hanging or desk accessory meant to symbolize wealth and historical prestige, rather than functional currency.
