Contrary to what many people think, the caravan is not just about selling the goods it carries, but rather just the beginning.

After selling the goods, you will get a lot of money, and at this time, you will often spend money to buy some local specialties in the local area, and then bring them back to earn a second difference.

And what the caravan brought back this time was basically some goods that could be sold at a high price in the principality, or raw materials that Luo Ming urgently needed.

Silk, tea, spices, a hundred kilograms of iron...... In addition to this, there are a number of silver ingots and coins.

On the other side of the mountain, the price of silver was nearly 20% lower than in the Principality, or the Principality was relatively short of silver, so the price of silver was higher than elsewhere. Theoretically, one gold coin is equal to ten silver coins, but this is often not the case in real life.

Simply melting these silver coins (to prevent them from being seen to be from the Silk Tea Road) and then selling them in the principality along with those silver ingots can actually make a fortune, almost a quarter of the profit.

But that kind of technique is too crude, as a visitor in the 21st century, although Luo Ming is not an entrepreneurial expert, but at least he has been exposed to a lot of things: where is it more profitable to sell raw materials after rough processing, and where is rough processing more profitable than fine processing?

Although there are still some differences between the way Luo Ming is used and the way it is processed into finished products and then sold, the reason is still the same.

In short, with this silver, one of Luo Ming's plans can be put on the agenda.

He had been working on hydraulic hammers for more than a year, and the hammers powered by waterwheels were ten times heavier than the iron hammers that ordinary people could use, and they could be used for other purposes besides forging steel.

For example, attaching a steel mould to the hammer head allows the pattern and pattern to be hammered directly on the softer metal.

There is no doubt that silver is naturally a relatively soft metal.

Luo Ming was going to use the silver directly to make silver coins, because silver coins could be properly mixed with some cheap metals compared to simple silver ingots, so there was more room for profit.

"Of course, if it's just like this, it won't show my Luo Ming's ability. ”

"So what are you going to do? We don't have a professional jeweler in our territory......"

Luo Ming bought a pass for Granty, and saw that she hadn't fully figured it out after thinking about it for a long time, and even pouted, before answering with a smile and opening a small box, taking out a few pieces of paper from it, and handing them to Granty.

"What do you think this is?"

Granty took it and looked at it closely.

Although the paper is a little harder, it is stronger and smoother than ordinary writing paper, and has a neatly cut rectangle.

On these pieces of paper, there are three colors, black, red, and the pale yellow of the paper itself, interweaving intricate patterns.

On the right side of the piece of paper is a bust of Luo Ming, on the left side is printed the words "equivalent to 10 copper coins", and on the back, there is a coat of arms of Luo Ming, and the words "no imitation and no rejection" are written.

Another piece of paper is larger, with indigo in addition to black, red, and paper colors, which occupies a large area. On the top of it, the words "equivalent to 1 silver coin" are written.

In addition, there is a yellow piece of paper with the words "equivalent to 1 gold coin" written on it.

This is a sample of the banknotes that Luo Ming is about to issue, although as a viscount, he can only be regarded as the middle in the noble sequence, but he is also a ruler in his own territory, and has almost all the real power.

It may be a bit of a no-no to issue a new silver coin on a large scale, but Loming's note is nominally called "Schönbrunn Central Bank Bank Notes," or Schönbrunn Bills for short.

Bank bills are similar to IOUs, passbooks, or bank bills. In fact, there were some such businesses in the principality, for example, when a rich person travels and does not want to carry a heavy amount of gold and silver with him, he can give the gold and silver to a bank, and then use the bills issued by the banker to go to another bank in a different place to withdraw the gold and silver.

For example, some rich people are worried that their property will be stolen, and some people will provide vault business, as long as they pay a certain storage fee, the rich can store their property in the vault, and then withdraw money with the bills.

Sometimes, the bill itself is used as a banknote, and the bill is paid directly, which saves the fatigue of carrying so much gold and silver.

The bank notes issued by Luo Ming are just a step further on this basis: they can exchange the same amount of physical coins with the Schönbrunn coupons, or exchange coins and metal ingots for Schönbrunn coupons, the latter generally only charge a negligible handling fee, and the former only needs to pay a 5% exchange tax. Of course, you must make a reservation in advance for a large amount of money, but you can enjoy some discounts.

In addition, Lockin stipulated that no subject of Schönbrunn could refuse to accept Schönbrunn vouchers, and that tax collectors could not refuse Schönbrunn vouchers when collecting taxes, ensuring that a certain percentage of taxes must be paid with Schönbrunn vouchers.

Naturally, there are some mysteries in these policies, although Luo Ming is not an economic expert, but with Aya's help in detail, there is generally no problem.

Of course, Luo Ming came up with this Schönbrunn coupon, naturally not simply to facilitate his subjects to carry lighter banknotes.

He did not issue Schönbrunn coupons one by one according to the number of silver and copper coins he held, but simply made a plan to print 500 gold coin coupons, 10,000 silver coin coupons, and 20,000 copper coin coupons equivalent to ten copper coins. In fact, the reserves in the treasury of the "Schönbrunn Central Bank" consisted of only 300 gold coins, 4,000 silver coins or silver ingots equivalent to silver coins, and 30,000 copper coins.

Of course, it is impossible for so many Schönbrunn coupons to be put into the market directly at once, otherwise it will definitely be fried, and he will slowly distribute these Schönbrunn coupons through wages, government procurement, etc.

Although the amount of Schönbrunn bonds issued was more than the reserves, and if all of them were required to be exchanged, the central bank would be emptied of the treasury and would not be able to pay the bills, and the credit of Schönbrunn bonds would be bankrupt, but this is basically impossible to happen.

First of all, there is a 5% tax to pay when exchanging Merbrunn coupons for gold and silver, although this tax is not much, but the average person weighs it and is not willing to suffer such a loss in vain, so he will not easily come to exchange it.

In addition, tax collectors also have indicators, and a certain percentage of Schönbrunn coupons must be collected in the annual tax revenue, and no matter what, people will keep a few in their hands to cope with the taxes.

Even if many people came together and asked for gold and silver at the expense of being charged a 5% tax, Luo Ming still had a way to deal with it.
