The Hindu deity Siva was portrayed on the backs of the coins.

"The currency helped the dynasty to be accepted by newly conquered territories and played an active part in the expansion of the empire," says Wang.

Among the sculptures on display is a Buddha sitting in a hall decorated with Corinthian columns on either side.

"The exquisite piece presented a Buddhist sermon alongside a symbol of Greek architecture and achieved wonderful harmony," says Wang.
