the maitrakas continued coinage styles established by their predecessors; the guptas and the western kshatrapas. large number of copper and silver coins are found in vallabhi and elsewhere. there are two types of coins found. the first were 6" in diametre and weighted 29 grains. they were perhaps earlier coins modeled after the western kshatrapa coins. later coins were similar to the gupta coins in shape, size and legends. like gupta coins, they were not made of pure silver but silver-coated.
