Abstract
Cronebane Halfpenny Tokens is a quick identification key to all the known counterfeit tokens that were produced between 1789 and 1816. The tokens were used by the Irish Associated Mining Company based in County Wicklow in Ireland to pay their workers during the coinage shortages during the reign of King George III. \n \nThe Cronebane halfpenny became the most well known and most widely circulated Condor or trade token with 1.67 million original tokens produced by Mathew Boulton at his Soho Works in Birmingham. However, an estimated 3.0 to 4.5 million counterfeits tokens produced afterwards entering general circulation from the British Isles to Canada and Australia. This new key allows the none-specialist coin collector to rapidly identify these interesting and affordable coins that have wide historical significance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
