Tiger Tongue and Canoe Money of SE Asia

Silver, billon and bronze denominations of proto-coinage
ingots in the shape of tiny boats or also what is known
as "tiger tongue" money (bottom image). Shapes were
stamped into the metal. This type of currency was issued
in the NE Thailand region of Isaan and also the Lan
Chang Laotian kingdom which bordered Isaan to the north.
I have several types which vary in size from 5-18cm. It is
estimated that this currency was traded from the 13th up
to modern days in the late 1800s.
