Baron Hubert, Baron Adolf, and Steward Osborne each took a coin and looked at it carefully, and from time to time they compared the two gold franc coins on the table with the silver tinnings.

"Master William, the appearance of this penny coin is so neat and round, the pattern on it is clearly visible, and there are no irregularities, but even the finest gold coins cannot guarantee that their appearance is round and smooth, and it is very common for the handwriting to be blurred and irregularly distorted. How does this coin do it? Steward Osborne asked suspiciously.

"These three penny, shilling, and gold William coins were not struck in gold and silver and then struck in a mold, but were stamped directly on the die with a hydraulic machine, which is why they are so perfect.

Such a beautiful appearance and pattern is a weapon that I use to promote this set of gold and silver coins, and all the currencies in circulation in the market today are not as beautiful as my set of gold and silver coins, and I believe that as long as this set of gold and silver coins is in circulation, it will be able to expel all other gold and silver coins on the market. William said confidently.

The first step in the minting of gold and silver coins is the melting and rolling of the slats. The molten precious metal is first cast into the required size slabs by a continuous casting machine, the surface is mechanically milled to remove impurities, and then the slabs are cold-rolled under extremely demanding operating conditions.

In order to ensure that the surface of the rolled plate is smooth and clean, and does not affect the quality of the finished product in the future, it must be guaranteed to be clean throughout the processing process, and the surface of the plate is not allowed to have scratches, pits, corrosion and other defects. After the heat treatment annealing, the mirror-like strips with very tight thickness tolerances are rolled out on a dedicated hydraulic finishing mill.

After finishing rolling, the precious metal strips can be punched blanks, also known as blanking. It is a stamping process that uses a die to separate the metal plate (strip) on the hydraulic stamping machine.

The blank must be punched to ensure that the smallest burr and the best edge are obtained, and any contamination, scratching, scratching must be avoided, and then the blank must be brightly annealed in a protective environment to reduce the surface hardness of the blank.

When annealing, it is necessary to strictly follow the heat treatment process regulations to control the grain size of the metal material and avoid the oxidation of the surface of the blank cake, otherwise the surface of the metal coin is not easy to get the due mirror finish.

The blank cake is polished after bright annealing, and the polishing can be carried out according to different requirements by cloth wheel polishing and mechanical polishing, and the surface of the blank cake is cleaned and dried with a special cleaning agent, and the blank cake has become mirror and clean. Put the mirror-surfaced, shiny perfect blanks in strict accordance with the specified number in a clean container with a lid to prepare for embossing.

In order to mint gold and silver coins with exquisite craftsmanship and artistic charm, it is necessary to design and produce a qualified stamping mold. One of the most important technologies in minting is the design and manufacture of molds.

All commemorative coins are designed with two faces, the front and the back. The design of the pattern is the first process of coinage mold making, and it is the embodiment of art art in precious metal currency.

The design of the design on the gold and silver coins should be able to fully reflect the harmony and unity of generality, nationality and singularity, and at the same time take into account the feasibility of the mold-making and embossing processes that could be achieved in the Middle Ages.

"Is their gold and silver content the same as the one marked on the north, if that is the case, plus the cost of casting, we will lose money, and the more minted we will lose." Baron Adolphus took the 'Golden William' gold coin in his hand, looked at William and asked.

William took the 'Gold William Gold Coins' handed over by Adolf, held it in his right hand and shook it towards the three of them, and said confidently: "Of course not, Uncle Adolf, the weight of the gold and silver coins in your hands is not equal to the weight marked on them, and their gold and silver content is not close to 100%, these gold and silver coins are mixed with a certain content of copper, tin, lead and other base metals.

Among them, 'Gold Louis' has the highest gold content, reaching 91.6%, also known as 22k pure gold coins, which is higher than all gold coins on the market, so its appearance is the most exquisite and the most perfect color.

On the other hand, the weight of 'Golden William' is not the 5.28g of gold and its equivalent of a pound of silver, it weighs only 4.5g, so we can make a 20% profit for every 'Golden Louis' minted.

As for the 'shilling' silver coin, this commonly used currency weighs 21.6g, which is the same weight as the one marked on the reverse, but its silver content is only 73%, and the rest of the composition is mainly copper and small amounts of tin and lead, this silver-copper alloy is not only bright in color, but also hard and wear-resistant, not as soft as sterling silver.

Finally, there is the 'penny' silver coin, which weighs 1.08g and contains only 66% silver, while the rest is doped with base metals such as copper, tin, and lead.

As a result, I am confident that I can make unimaginable profits by minting gold and silver coins, not to mention the fact that the technology I use to cast coins by hydraulic stamping allows me to produce gold and silver coins with less labor and raw material costs and with greater efficiency, which is unmatched by other countries. ”

"Then I will be at ease, and the minting of William, Shillings, and Pennies will not only increase my influence in Normandy, but will also be beneficial to the finances of the Duke's Palace, and we should spread them out at once." Baron Adolf clenched his right fist excitedly and said in an uplifting tone.

The butler Osborne on the side also followed Baron Adolf's words and said, "Young Master William, the Normandy Bank I am in charge of for you can issue this set of gold and silver coins for you.

Our Normandy bank has opened a large number of branches in Normandy, Flanders, Paris and Brittany, and is currently planning to enter the kingdoms of Castile, León and Galicia, as well as the French principalities of Aquitaine, Poitou, Gascogne, Champagne and Burgundy.

And the various caravans under the command of my Normandy consortium, they can use these Normandy gold and silver coins to settle their wares.

You must know that the full-body plate armor and half-body plate armor and all kinds of weapons and equipment produced by us are hard currency in the vast number of Europa, and the few great victories you have won have made a big advertisement for our weapons and armor.

As long as you can mint enough gold Williams, Shillings, and Pennies, I can get them out there as fast as I can. ”

"You have done a good job, Steward Osborne, and I will entrust you with the task of issuing the golden William, the shilling, and the penny." William said with relief: "As for your concern about the lack of mintage, you can rest assured that with the millions of pounds of silver worth of gold and silver coins and all kinds of gold and silver bullion in my hands, and with the high efficiency of the hydraulic machinery, I am fully confident that I will be able to mint enough gold and silver money."

A mint with an annual production of more than a million gold and silver coins is currently being built on the banks of the Seine, and in the next three months my coins will be able to be minted on a large scale. ”

Rao is full of confidence in front of everyone, but William still does not take it lightly. Every day when he had free time, William would go to Claude's to supervise the progress of the work at the mint, and in the evenings he would take time to discuss the issue of money with Osborne's butler.
