MINT ERROR SPECIMEN REPORT & VARIETY DIAGNOSTIC
Denomination : Australian One Penny
Year of Issue: 1916-I (Struck at the Calcutta Mint, India, during World War I) [x].
Planchet Anomaly (Thin Planchet Error): Confirmed via digital scale diagnostics at an underweight profile of 9.2 grams (Official standard mint specification is 9.45g) [x]. This verified deficit provides absolute proof of a genuine Thin Planchet factory defect, resulting from substandard bronze strip thickness dimensions prior to blanking truncation. Completely non-magnetic (tested) [x].
Grade & Condition Assessment: Grades at a strong, choice Fine to Very Fine (F-VF). The specimen retains excellent structural definition with individual separation on the band pearls of King George V’s crown, surrounded by an authentic chocolate-brown copper oxidation patina [x].
Primary Striking Anomaly (Misaligned Die): Linked directly to the thin planchet profile, the design matrix is shifted sharply towards the 1 o'clock position [x]. The upper right denticles are tightly compressed against the rim, while leaving a wide, blank metal crescent margin along the lower left quadrant (7 o'clock to 8 o'clock) [x].
Obverse Field Anomaly (Die Clash): Features a definitive Die Clash error within the obverse fields. Ghostly, mirrored design elements from the reverse matrix (ornamental scrolls and beaded border) are visibly impressed into the negative background spaces directly in front of the King’s profile (forehead, nose, and chin lines) due to insufficient planchet resistance during the minting sequence [x].
Comprehensive Obverse Doubling (Doubled Die Obverse - DDO): Confirmed Class-I rotated hub doubling across the obverse lettering. Crisp edge-notching and dual-layered contour lines are highly visible, particularly within the letters "G" and "E" of "GEORGIVS" and across the "OMN:REX F.D." legend block [x].
Comprehensive Reverse Doubling (Doubled Die Reverse - DDR): The doubling extends comprehensively across the reverse matrix. Pronounced structural split-serifs and notching are evident on the letters "E" and "M" of "COMMONWEALTH", coupled with secondary strike lines running through the central "ONE PENNY" inscription [x].
Doubled Mintmark & Doubled Date Logotype: Close-up diagnostics reveal a rare Doubled Mintmark ("I"), displaying a secondary raised vertical matrix layout on its right flank [x]. Furthermore, the "1916" date sequence exhibits definitive Doubled Die characteristics, showcasing clear edge-notching on the digits "19" and distinctive overlapping contour lines on the "16" sequence [x].
⚠️ PROMINENT VARIETY EXTRA REMINDER: Please pay extra attention to the obverse alignment. This specimen features a textbook Misaligned Die (Offset Strike) anomaly shifted significantly towards the 1 o'clock position. The upper-right denticles are heavily compressed against the rim matrix, while the lower-left quadrant (7 o'clock to 8 o'clock position) displays an extraordinarily wide, blank copper crescent margin. This distinct misalignment is an authentic factory production mint error, completely separate from post-mint damage.
Summary: An extraordinary, museum-grade multi-error pre-decimal copper masterpiece [x]. Exhibiting a rare combination of an underweight Thin Planchet, dual-sided die doubling (DDO & DDR), a prominent Die Clash, a doubled date, a doubled mintmark, and a misaligned strike, this specimen represents a pinnacle of structural minting anomalies [x].
