This is an Irish pre-decimal bronze coin, specifically a half penny (leath phinghin) dated 1928. The obverse side shown features the iconic Cláirseach, the Brian Boru harp, which serves as the national emblem of Ireland. To the left of the harp is the inscription 'éire' (Ireland) and to the right is the date '1928'. The coin is composed of a bronze alloy (typically 95.5% copper, 3% tin, and 1.5% zinc). Physically, the coin displays a deep, dark brownish-red patina, which is characteristic of circulated bronze coins that have aged over decades. The striking appears to be well-defined, though the surface shows signs of significant wear, including minor scratches, environmental toning, and softened edges on the harp's strings. There are visible 'bag marks' and small dings on the field of the coin consistent with its age and circulation history. This specific coin belongs to the first series of coinage issued by the Irish Free State, designed by artist Percy Metcalfe. His initials 'PM' are often found on these issues, though they are obscured here by wear. The craftsmanship represents the transition of Ireland into an independent state, utilizing traditional Gaelic iconography in a modern numismatic format.

I have examined the provided image of the 1928 Irish Half Penny (Leath Phingin). As the first year of issue for the Irish Free State, this Percy Metcalfe design is historically significant. Based on the visual evidence, the coin is in a 'Very Fine' (VF) to 'Extra Fine' (EF) circulated condition. The patina is a pleasing chocolate brown, though the softening of the harp strings and visible dings in the fields indicate significant time in circulation. The strike remains centered, and the legends are legible, which maintains its appeal for type-set collectors. Market demand for 1928 Irish bronze is steady but high-volume. While this was the inaugural year, the mintage was relatively high (over 2.8 million), meaning high-grade uncirculated examples are the primary drivers of significant value. Current comparables for circulated examples typically realize between $5 and $12 at auction. Factors limiting the value include the environmental toning and bag marks, which prevent it from reaching 'Choice' or 'Gem' status. Regarding authenticity, the typography and harp details appear consistent with genuine Saorstát Éireann issues. However, a digital image cannot confirm weight (target 5.67g), diameter (25.5mm), or metallic composition. A physical inspection is required to rule out contemporary counterfeits or cast replicas. Full authentication would involve precise weighing and an examination of the rim for any signs of joining or filing. For a definitive numismatic grade, submission to a third-party service like PCGS or NGC would be necessary.
