1/8 Tanga - Carlos I Lisboa mint

The fractional tanga denominations struck for Portuguese India at Lisbon in the early 1900s were a pragmatic response to the entrenched local currency system in Goa, where the tanga — rooted in Indo-Portuguese monetary tradition stretching back to the 16th century — remained the practical unit of everyday commerce. Lisbon-struck pieces for this territory are distinguishable from those produced at the Nova Goa mint, and the two sources serve collectors as a meaningful point of differentiation within the type.

The 1901–1903 window corresponds to a period of administrative consolidation in the Estado da India, when Lisbon reasserted tighter control over colonial coinage production.
