Half Vellichakram of Travancore dynasty is considered by the archaeological department as the smallest coin in the world. But many numismatists object this claim.

Obverse: A beautiful designed wide crescent is visible in this Chuckram. Reverse: Here twelve pellets within a crescent and two stalks of flowers within lines and dots are present.
