Definitely Raja Raja Chola Indian coins. The lakdiva site primary concentrates on Sri Lanka. The so-called "Octopus Man" design was used for hundreds of years through out South India and Sri Lanka with varying designs. Most people have only seen the Raja Raja and Sri Lankan varieties. I haven't gotten around to taking pictures of some of the other coins in my collection, but here are three:
Chola: Kulottunga Chola I (1070-1120) Kasu (MCSI-345)
Obv: King half seated, with raised arm on right; Tamil legend beneath raised arm - Ku (கு)
Rev: Standing man, with lamp on left and group of pellets on right
Chola: Raja Raja I (ca. 1007) AE Kasu (Biddulph-21)
Obv: King half seated, with raised arm on right; Devanagari legend beneath raised arm; श्री राजा राजा (Sri Raja Raja)
Rev: Standing man, with lamp on left and fish on right, representing the the Pandya conquest
Arya Chakravartis of Jaffna: Anonymous (ca. 1284-1410) AE Massa (MNSI-862)
Obv: Seated king on left facing right with Tamil legend செது (SETU) vertically below his arm.
Rev: Standing king with crown consisting two lines and a dot, trident on left under raised right arm. A bull couchant vertically with a circle before it. All in bead circle. group of spheres on right, surmounted by crescent.
BTW, several naive ebay sellers have labeled these coins as "Octupus Man", and in reality, the other so-called extra legs are really his garment (called dhoti). See the following thread for more types:
