Heavily Worn Copper Coin with Profile Portrait

The item is a circular, metallic coin, likely made of copper or a copper alloy, given its predominantly dark green and reddish-brown coloration, which suggests significant oxidation and patina formation characteristic of aged copper. The coin's surface appears heavily worn, obscuring many fine details of the design. The overall color is a mottled dark green, with areas of brighter reddish-brown showing through, particularly near the center of the obverse (front) side, indicating possible areas of less corrosion or surface rubbing. The obverse prominently features a profile portrait of an individual, facing right. While the specific details are indistinct due to wear and patination, the overall silhouette suggests a monarch or historical figure, possibly a female, given what appears to be a crown or elaborate hairstyle. Around the rim, there are faint traces of text or legend, but the individual letters are unreadable. No specific manufacturing marks or dates are discernible from the image, but the style of the portrait and the evident level of wear and patination indicate a considerable age, likely from the late 19th or early 20th century, consistent with coins circulated for a long period. The edges of the coin are not visible, so characteristics like reeding or plainness cannot be determined. The coin exhibits heavy wear, significant environmental damage in the form of deep patination, and possibly some surface pitting, all of which contribute to a lower grade condition.
