Irish-style copper-alloy coin bearing a '1979' date

This item is a circular coin appearing to be composed of a copper-colored alloy, stylistically consistent with the pre-Euro decimal coinage of Ireland. The obverse side shown features the Irish Harp (Cláirseach), which is the traditional national emblem. To the right of the harp, the word 'ÉIRE' is inscribed in a Gaelic-style typeface, and to the left, the date '1979' is visible. The coin exhibits a reddish-brown tone typical of copper-based compositions like bronze. Based on its visual characteristics and markings, it is consistent with a two-pence or half-penny piece from that era, though the denomination is not visible in this view. The condition shows moderate circulation wear, with softened details on the harp strings. There are noticeable patches of greenish oxidation or verdigris along the right edge near the lettering, suggesting exposure to moisture or environmental elements. All identifications are based on visible markings that are consistent with official currency but remain unverified without physical expert inspection.

Based on my visual review of the image, the coin appears to be an Irish decimal bronze piece dated 1979, possibly a half-penny or two-pence based on the scale and typeface. I can see the harp emblem and ‘ÉIRE’ inscription consistent with standard Irish coinage of that period. However, I cannot verify the exact metallic composition or weight from a photograph, and physical inspection would be required to rule out contemporary counterfeits or specialized mint errors. The coin displays moderate circulation wear and notable verdigris or surface oxidation on the right side, which negatively impacts its numismatic grade. In the current market, copper-alloy coins of this era were minted in high volumes, making them very common. The estimated value of $0.05 to $0.50 reflects the typical market range for a circulated, uncertified example of this type. This value assumes the coin is a standard circulation issue; if it were a rare proof or a specific variety not visible here, the value could increase slightly, whereas a modern replica would have essentially no collector value beyond its scrap metal content. To confirm its status, an expert would need to perform a density test, weigh the piece to the nearest milligram, and examine the edge milling under magnification. Because this is a high-mintage year, the market demand is generally low among collectors unless the specimen is in pristine, uncirculated condition.
