Standard Vira Raya design. 8mm, 0.36 grams. Minted in Cochin by the native Rajas. Hans Harrli "Gold Fanams" #1.14.
These fanams of the Rajas of Cochin were commonly known as the "topa fanams" ("cannon fanams") - the design on the reverse was interpreted as a cannon over a heap of cannon balls. Herrli suggests that this was not just a common name, but an actual intended design.
