Circulated Coin or Token with Heraldic Shield Motif

The item appears to be a heavily circulated coin or medal, likely made of a base metal such as copper or a copper alloy, given its dark, oxidized appearance. The surface exhibits a significant amount of wear and accretion, obscuring fine details. The primary visible feature is a central design resembling a shield or escutcheon, which is divided into multiple sections. Within this central emblem, there are faint, raised elements that might represent heraldic charges or symbols, though they are largely indistinct due to wear and surface texture. Surrounding this central design, there is a circular legend or inscription, with only a few letters discernable. On the left side, the characters 'Z B' followed by '3' are somewhat visible, while on the right, shapes resembling 'Y' or 'V' and 'I' can be faintly made out. The overall impression is one of age and extensive use, suggesting it has been handled frequently. The texture of the metal shows pitting and irregularities, indicative of environmental exposure or corrosion, rather than just smooth wear. The raised edges of the design elements are largely flattened, and the fields are dulled. The craftsmanship, though difficult to assess fully due to condition, suggests a struck piece, typical of coinage or medallions. Without clearer details of the inscription or central motif, specific identification of the issuing authority or date is challenging. However, the style points towards an older European origin, possibly from the 17th or 18th century, given the appearance of the heraldry and lettering style, though this is a preliminary assessment based on limited visual information. The visible condition issues include significant patination, surface abrasions, and a lack of sharp detail.
