Which is the most expensive ingot in Yunnan archway?

Yunnan Yuepaifang Yuanbao is a cultural relic of Qing Dynasty collected by Shanghai Bank Museum. It is very old, so it is of high value.

The archway ingot, named after the archway-like building, weighs about 180g, with an average silver content of about 96%. It is also called "loss assessment bank" because it is supervised by the loss assessment system. There are three identical seals printed on the front of the archway ingot.
