Ratna Deva II - Kalachuris of Ratnapura fractional masha

The Kalachuris of Ratnapura — a branch dynasty operating in what is now Chhattisgarh — were effectively squeezed out of regional dominance by the Paramaras and Chedis across the eleventh and twelfth centuries. Ratna Deva II's reign represents one of the dynasty's last periods of meaningful independent coinage before Ratnapura's political weight diminished entirely under Kalacuri pressure from the north.

Fractional mashas at this weight were struck for local market transactions where the standard masha was too high a denomination for daily exchange. The Mitchiner range 666–670 covers several die variants, and attribution of individual pieces to specific rulers within that span remains contested without accompanying inscriptional evidence.
