Cooch Behar. Jagaddipendra Narayan Nazarana 1/2 Rupee CB413 (1923) MS65 NGC, KM-X11 (previously KM225). Slightly reflective luster sits beneath a pleasing layer of earthy patina and the strike is bold and fully formed. A very scarce issue, and as the single finest graded example at NGC, especially notable for its quality.
Estimate: 1500-2000 USD
