Bull kneeling left within a dotted border / Maharaja Sri in a circle in Brahmi. 20-ratti standard - 11mm, 1.30 grams. Mitchiner 4730-4732 var. Rare.
This type with a kneeling bull seems to be unpublished in the standard references. The reverse legend is just "Sri Maharaja" ("Venerable Maharaja"). The attribution to Deva Naga is done on the basis of style.
