The "Lohiya Paisa" designation — lohiya meaning iron in Nepali — reflects the deliberate iron content introduced into these copper coins, which gave them an unusually dark surface and magnetic properties distinct from standard copper issues of the period. The Nepalese monetary system of this era was notoriously inconsistent, with coins struck across multiple Kathmandu Valley mints under successive Shah rulers, and weight standards fluctuating considerably within a single reign. The eighty-year attribution window in the reference is an honest admission that die linkage and reign assignment for these pieces remain unresolved.
