The texture of gold is soft, and the purer it is, the softer it is, so there are often plots in TV where people use their teeth to identify the identity of yellow metal.

In general, the yellow metals that appear in nature are nothing more than gold and brass, brass is very hard, and biting with teeth will not only not leave tooth marks, but also break teeth in serious cases.

The many treasure hunters stared wide-eyed and saw a clear tooth mark on the metal plate, which Hans had just bitten on. The two rows of tooth marks are neat, and they reveal a more dazzling yellow color after being bitten!

This scene made everyone's eyes hot, and the crowd was in a commotion and crowded forward.

Godzilla lifted the hydraulic shears and said coldly, "Are your bones harder than iron plates?"

The treasure pickers were startled, and one of the people who rushed to the front looked up at Godzilla with a gloomy face, and quickly sneered: "No, no, man, you misunderstood, I want to help detect whether this is gold." Look, I've got magnets here. ”

"yes, my guy just got a big magnet, you know, he can help you identify this thing. His partner also quickly explained that Godzilla and hydraulic shears were not ordinary.

Magnets are also a way to roughly examine gold, gold does not contain magnetic metals, and if something can be attracted to magnets, it is not gold.

But some pure brass also does not contain magnetic metals, so this is just a rough way to test, but the treasure picker makes a reason for himself.

The treasure picker took the magnet up and spun around, then turned around and said, "This is really gold, it is not magnetic!"

Someone shouted: "Magnet inspection is useless, use unglazed ceramics to test, Li Boss, Fu Boss, unglazed ceramics can test the authenticity of gold." ”

Unglazed ceramics will leave gold marks on gold products, and other metals will produce black marks, which is indeed a more reliable method.

Li Du waved his hand casually, there were ceramic products in the warehouse, and someone went to find a plate and rushed over with interest.

Hans, who was standing in the car, carefully examined the metal plate, and when the treasure hunter approached, he pushed the treasure collector away, and said happily: "No need to inspect it, no need, this is definitely gold!"

Conrad was unconvinced, and said, "Just because you checked it with your mouth?

The treasure hunter next to him laughed, and Conrad also felt that his retort was very powerful, and laughed equally happily.

Hans said, "Fool, my mouth is the same as your parents', with only teeth, tongue and saliva in it, but I still have a pair of eyes that I can examine with my eyes!"

He asked Li Du to stand on the pedal of the car, pointed to the front of the metal plate and said excitedly: "Do you see it, do you see anything there?"

Li Du glanced at it and said, "How many letters are there, FRB-Dallas, followed by an 11?

"FRB-Dallas (11), this is an abbreviation for Federal-Reserve-Bank-of-Dallas, 11 refers to District 11, the 11th Federal Reserve District of the Federal Reserve's Gold Bank!" Hans exclaimed.

Listening to Hans's words, the treasure pickers became agitated again, and several of them ran over to avoid Godzilla's blockade, and they jumped to look at the roof of the car, and said, "Really, FRB-Dallas (11), this is the gold of the Federal Reserve!"

The Federal Reserve Bank of the United States is the most powerful bank in the world, with the most dollars and gold in the world, located at 33 Liberty Avenue in New York.

The bank actually includes twelve banks and their twenty-five regional branches throughout the United States, with Dallas having Bank No. 11 and known as Federal Reserve District 11.

According to the Federal Reserve Bank, the country's gold reserves are distributed in the vaults of twelve banks, which are then allocated by the head office in New York.

Local gold first enters the Regional Reserve, where it is stored in gold ingots, which are stamped with the identification code of the Regional Reserve to which they belong.

For example, FRB-Dallas (11) refers to the fact that gold belongs to Federal Regional Reserve Area No. 11 and is stored by the Federal Reserve Bank of Dallas.

Hans said optimistically: "This is definitely real gold, pressed into a gold plate from gold ingots from 11 Federal Regional Reserve Districts, I guessed correctly, absolutely." ”

Conrad scoffed, "Who would be so stupid to press gold ingots from the Federal Regional Reserve District into gold plates and show up in the border areas......?"

At this point, he seemed to suddenly think of something, and closed his mouth suddenly, his eyes straightened.

A treasure hunter next to him said what he thought: "God, this is the batch of gold that the Bank of Dallas was once robbed from the plane, right?DB-Cooper Gold?!"

As soon as his words came out, many people immediately responded:

"Is the logo FRB-Dallas (11)? That's the gold that was stolen from the plane in Dallas, right?"

"Oh my God, we've got a legend, it's true, it's all gold!"

"Hurry up and weigh it, one hundred and twenty kilograms of gold, DB-Cooper snatched one hundred and twenty kilograms of gold at that time!"

Li Du looked at Hans in confusion and asked, "What are they excited about?

Hans tore at his collar excitedly and asked, "DB-Cooper Gold, you don't know about the gold heist of the seventies?"

Li Du pushed him away and said, "I wasn't born in China in the seventies, so how do I know what happened in your United States at that time." ”

Hans exclaimed, "Then you should have seen the relevant introduction, this case is still on the Internet by the FBI, and TV shows will bring it up from time to time to discuss it!"

"Anyway, I don't know, do you say it or not?" Li Du said impatiently.

Hans raised his hand and said, "Don't be angry, my good brother, don't be angry, I said I'll say it right away, but if you don't know, I'll have to explain this case for a long time, you have to be patient......"

"Say!"

"OKOK!" Hans said, licking his lips, "it happened in 1971, brother, when the Bank of Dallas transferred a shipment of gold to Los Angeles. ”

"You know, it was the worst of the Cold War, and the country was allocating a lot of resources to the military industry and defense, so other places had to be frugal, like the banks. ”

"Now banks use special planes to transfer gold, but not at that time, they used civil flights to carry it by the way. ”

"So, the problem happened, a guy named DB-Cooper boarded the plane, and then when the plane flew into the air, he took out his suitcase and assembled a bomb on the plane......"

"Boss Fu, what you said is not right, let me introduce it to Boss Li. "His name is not DB Cooper, that's what the media said, his name is Dan Cooper, I can assure you, his name is Dan Cooper, because my grandfather was one of the hostages on the plane at that time!"
