This thing...... Actually, it's quite troublesome, but not to mention it will cause confusion, so here is a substitution ratio, which is considered a supplement (after all, it's another world!)

A large gold coin is equal to a pound of gold, not as a means of circulation, but only as a reserve and transportation, and the book is based on this for the calculation of trade, taxes, indemnities, etc.

Twenty small gold coins are equal to one large gold coin, which is the currency used in normal commercial trade (and also a necessary prop used by various brain-dead second generations to smash people), which belongs to the negotiable category.

One large silver coin is equal to a pound of silver, a must-have store of valuables for a normal medium-sized family, and the purchasing power is almost equal to 4,500 yuan (which was already a lot of money in ancient times). Ten large silver coins are equal to one large gold coin, and the value is basically the same.

Twenty small silver coins are equal to one large silver coin. Generally speaking, the salary paid in the book is generally paid with this and this.

zuihou is the sad copper plate, belonging to the category of change and auxiliary coins, 200 copper plates are equal to a small silver coin, almost 4 cents of purchasing power, ancient food is actually not cheap, according to the "Wanderings of the Bitter Child" (at that time it was already the Renaissance), twenty Su ( Copper plate) can sell a black bread of about 2 catties, after I carefully weigh it, I think it is still very reasonable, the size of the copper plate is not consistent, and it is more detailed and regional than gold and silver coins in the division, so I will not explain much.
