1/2 Rupee / Deb Period III

Bhutan's coinage during this period was produced by hand-striking at small local mints, resulting in enormous variability in flan preparation, die alignment, and alloy consistency — brass and copper pieces from the same "issue" can differ so markedly that attribution by composition alone is unreliable. The long date range reflects continuous restrike practice rather than distinct annual production runs.

KM#15 encompasses multiple die varieties, and the boundaries between Deb periods remain contested among specialists, with attribution often depending on institutional collection history rather than firm documentary evidence.
