Here, Zhang Nan picked up a gold coin with a different pattern from the Nomisma coin, which was bent like a small plate, and said to Charlie: "This is the Heperon coin issued by the Eastern Roman Emperor Alexios I around 1100 AD, and the meaning of 'Heperon' is "super-proof" in Greek.

At this time, 800 years had passed since the time of Constantine I, and the weight of this gold coin was still standard Sulledus, and if it was not worn, it was still roughly 4.48 grams, but the shape became the usual saucer shape of the coins of the middle and late Eastern Roman Empire.

A gold coin of this size is about the size of 10 cents, and weighs between 10 cents and 25 cents, which is actually very convenient to use, and the ancients were also very clever. ”

The right size, which would be an American who would complain that the blood cents are too small or too big?

At this time, Huaxia also began to issue a coin with one yuan and five jiao, this kind of gold coin is slightly larger than the diameter of the plum blossom pentagon, the thickness is slightly thinner, if it is used by Huaxia people will not dislike its volume is too small or too small.

It's just that it's golden.

"Gold was really valuable at that time, and I'm not saying that the average person probably didn't earn 1 Suledus a month, so the mint in Constantinople at that time also produced two small gold coins as gold coins. ”

"This is it, Semisis, which means one-half, and is half the weight and value of the gold coin of Souledus.

And then there's the Teremisis, which you just thought was too small, which means one-third, one-third of the gold coins of Souledus. ”

As he spoke, he found a very small gold coin on the tablecloth, about the size of Teremisis (1/3), and handed it to Charlize Theron.

"Look at this, it's at least 1,200 years old, it's crudely made, it's an imitation of Western Europe at the time. ”

The girl took it and looked at it, "Who copied it?"

"The Visigoths, the Visigoths they established in the early 5th ~ 8th centuries in what is now Spain, southern France.

At that time, the Western Roman Empire was reimbursed, and the Germanic countries that took over Western Europe also imitated and issued their own gold coins in the name and head of the emperor of Constantinople, like this one, which I think is a copy of the head of Anastasius I in the park around 500 years.

However, at the beginning, the gold holdings in Western Europe were relatively abundant, and the quality of the Suledes produced in Western Europe was almost as good as that of Constantinople, but the economic conditions in the west were not comparable to those in the rich eastern Mediterranean, and there was no decent export of trade goods except for slaves.

From the East, not the East of China, is the meaning of the Eastern Roman Empire and the Arab world, and the Western Europeans who would be there could not do business directly with China.

The luxury goods purchased from the East depleted the gold reserves of Western Europe, so the imitation gold coins of Western Europe that can be seen today are basically this 'one-third of Tremisis', but at that time Western Europeans called this Suledus, or 'Su' for short.

Haven't you watched some movies and TV series that made early medieval movies, in which it is always said that buying a horse costs 'how many su', which is what you are talking about', but not Suledus of the Eastern Roman Empire.

Western Europe was poor, and by the 8th century, with the exception of Italy under the Eastern Roman Empire and Spain in Muslin, the production of gold coins had ceased altogether throughout Western Europe. ”

Charlize Theron looked at the gold coins in his hand and said, "The gold coins from 500 A.D. and the silver bars from 700 years later are in one piece, this treasure... It's long enough!"

Zhang Nan smiled, "It's not surprising that among the coin treasures found in the Huaxia Cellar, there is a difference of 1,500 years in minting time.

Gold coins are money at all times, and if I am the rich man who hides this money, then I will try to hide gold coins as much as possible, and such gold coins are worth a lot at that time!

It doesn't matter when it was produced, it has been stored from generation to generation, and it is normal for several generations or dozens of generations to be released. ”

"Then there was no gold for gold coins, what did they use?"

"Silver coins, silver if there is no gold, and then the quality gets worse and worse, and finally there is no way to gnaw it with dog teeth.

Charlie, in the era of "dog teeth", this gold coin is definitely the treasure of treasures, right?"

At this point, the girl has a question that she has to ask again, and her curiosity can't be stopped.

"How much was such a gold coin worth at that time?

I say this kind of minimal. ”

She was referring to the "Sus" of Western Europe, not the Sules of the Eastern Roman Empire.

"It's hard to estimate.

In the Middle Ages, there was a lot of money, and the value was difficult to estimate, but in ancient Rome, prices were stable. The daily life of people living in the Middle Ages was basically devoid of the commodity economy, and history went backwards.

The common people were self-sufficient, and even the nobles could only collect taxes and tributes in kind, and only some non-daily commodities that could not be produced by their own domain estates needed to be purchased.

Even so, most of the deal was bartering.

If one had to get a figure, it would only be possible to make an approximate estimate from the sporadic transaction records that had been handed down in Western Europe at that time, when prices were relatively stable.

About 1 su can buy 1 sheep, a pig needs to add a few denier silver coins weighing more than 1 gram, 1 cow 3 to 5 su, 13 su buy 1 pack horse, and the war horse is 5 times more expensive, at least 60 su.

One soe can also buy 1 Modi, which is about 17 liters of grain today.

A liter of wheat is about 780 to 760 grams, 13 kilograms.

As for the Eastern Roman Empire, there are many documentary records, in the same era of Constantinople,1 Sulledus, a gold coin three times heavier than the gold coin of the same name in Western Europe, a grain coin that could buy at least 12 matis, the price of grain was at most a quarter of that of Western Europe, the price of meat and livestock was basically the same as that of Western Europe, and the cattle and horses used for service were two or three times more expensive. ”

Charlie seemed to hear something and said, "Brother, wheat was more expensive than sheep at that time?"

There is always 13 kilograms of live sheep, and most of them should be more than that, just the same price as 13 kilograms of wheat?

Zhang Nan tilted his head, "How do I know."

Anyway, the literature says so, maybe bread was super expensive at that time, and Lenin's guard Vasily didn't say to his wife: "Honey, there will be bread, there will be milk!"

The girl laughed, this metaphor!

It's kind of interesting.

There are also a few gold coins that Zhang Nan doesn't like and Charlie recognizes, the Dinar of the Arab Empire.

The Roman coinage tradition was influenced not only by medieval Western Europe, but also by the Islamic world, where two currencies were long in the Arab Empire: the Golden Dinar and the Silver Dir Khan.

The dinar is an exact replica of the Roman Empire's Soledus, which is slightly lighter than the latter, weighing about 4.25 grams, while the dinar is a silver coin of about 3 grams, both minted at the Damascus mint.

From the 8th century onwards, Arab pirates and traders entered Europe in large numbers, and this type of gold dinar was also very popular in Western Europe.

As for Zhang Nan's dislike of the Golden Dinar, it is also simple: it is too ugly! Because idolatry is strictly forbidden, the coins of the Arab Empire often do not have a human statue.
