1985 British or Commonwealth Coin featuring Queen Elizabeth II (drilled)

The item is a circular metal coin, exhibiting a worn brassy or copper-toned appearance with some areas of discoloration, particularly a notable greenish-blue patina on the obverse to the right of the monarch's head. The obverse features a profile bust of a monarch facing right, identifiable as Queen Elizabeth II due to the visible inscription 'ELIZABETH II D.G. REG.' along the right rim. The date '1985' is clearly visible along the left rim, indicating its year of mintage. There is a distinct circular indentation or hole present directly above the monarch's head, suggesting it may have been used as a charm, pendant, or for some other purpose that required it to be affixed. The surface shows general wear consistent with circulation, with some loss of fine detail on the raised elements of the portrait and inscriptions. The coin appears to be of standard size for a circulated currency denomination from that era, though its exact diameter cannot be determined from the image. The craftsmanship aligns with mass-produced coinage, with crisp initial strikes now softened by wear. The visible damage (the hole) significantly impacts its numismatic value as a collectible coin, but it could hold value as a historical artifact or a converted piece of jewelry.

Upon examining the provided image of this 1985 British or Commonwealth coin featuring Queen Elizabeth II, I observe a circulating currency piece with significant alterations. The coin's overall condition is poor, exhibiting extensive wear consistent with prolonged circulation, evidenced by the softened details of the monarch's portrait and inscriptions. The brassy/copper tone and areas of discoloration, including a notable greenish-blue patina (verdigris), further indicate environmental exposure and age. Authenticity, based on visual cues such as the monarch's effigy and 'ELIZABETH II D.G. REG. 1985' inscription, appears consistent with genuine coinage of that era. However, the most impactful factor on its numismatic value is the distinct hole drilled directly above the Queen's head. This irreversible alteration renders the coin essentially worthless to serious coin collectors, as it no longer retains its original form or integrity as currency. The market for drilled coins is minimal, typically relegated to craft use or novelty items rather than numismatic investment. There is no rarity associated with a 1985 coin of this type, and the damage negates any potential collector demand. Therefore, its value is purely sentimental or based on its metallic content if any, which for a base metal coin is negligible. My assessment is limited by the sole reliance on an image; a full authentication would require in-hand examination to verify metallic composition, weight, and edge details, and to confirm the nature of the drilling. Provenance documentation would be useful if it were to be considered a historical artifact.
