The silver used by the ancients is the same as the RMB we use today, but the currency calculation method is different. It's one tael of silver, one tael of silver, one tael of silver, two taels of silver, all marked with marks, just like the face value of RMB now. It is weighed by hand, mainly to distinguish authenticity.
They will weigh it after receiving the money, but if it is filmed on TV, the audience will definitely scold it.
