If you find an old coin somewhere, it is useful to check it and check it well, it may be of high value and historical significance, which will help make a lot of money.

In her report, published by Intersting Engineering, writer Marcia Wallendorf spoke of the world's most valuable currencies.

Silver Dollar Flowing Hare
The silver dollar was the first coin issued by the US federal government. Founded in 1792, the US dollar coined the first silver dollar in October 1794. When it was issued, the United States followed the size and weight of the Spanish dollar.

The remaining silver dollars range from 120 to 130 pieces, and in January 2013 the Stax Powers showroom sold one of these pieces at a shocking auction for more than $ 10 million, making it the most expensive currency ever sold.

American Golden Eagle Coin
The author pointed out that this gold coin, equivalent to about ten dollars, was issued by the American Mint between 1792 and 1933.

Before 1933, when gold was no longer used in the US currency industry, the Eagle logo was placed on all US coins - including cents, dime and dollars - and the eagle coin.

The double eagle coin of St. Godens of America
In 1933, 445,500 coins were minted, but they were never circulated.

In the same year, President Franklin Roosevelt issued an executive order prohibiting the storage of gold coins and gold bars within the United States.

In 1934 Congress passed the Gold Reserve Act, ordering the dissolution of all but two of the double eagle coins, yet 20 of these coins disappeared and sold to collectors.

The US Secret Service set out to recover the lost coins and recovered nine of them, but one of them was included by King Farouk in his collection. When he was deposed in 1952, his items were auctioned, but the double eagle vanished.

In July 2001, the piece was transferred to the US Bullion Treasury at Fort Knox.

Bracher Duploon EB en Brest
This coin was made in 1787 by goldsmith Ephraim Bracher, making it the first gold coin of the United States.

In December 2011, a coin dealer sold a piece of these coins for an estimated $ 7.4 million.

American Liberty Head Nickel
It is said that only five coins still exist.There are two coins in a museum and three in the public.In August 2018, the Stax Powers auction sold one of these coins for $ 4,560,000.

Strangely enough, there was no record that the US mint minted the coin in 1913. In December 1919, a coin collector, Samuel Brown, published an advertisement in The New Psychiatrist offering $ 500 for Liberty Head Nickel Coin.

In the United States - precisely during the annual conference of the Collectors' Association in 1920 - Brown appeared with five coins and then sold them to Colonel Edward Howland Robinson Green.

The currency, which sold for nearly $ 5 million, was called the Ellisberg sample.

The story of Walton is perhaps the strangest thing. When the owner, George Walton, died in a car accident on his way to a coin show, his heirs tried to sell the coin at an auction, but the auction house considered it a fake and returned it to its owners.

This piece was kept in a locker in Walton's sister's house for 40 years. In June 2018, the piece was sold for $ 3 million to $ 4 million.

Bast Dollar "First Class"
According to the author, this coin is also known as "Boyd Liberty Dollars", which was issued by the American Mint during the 1830s, and these coins were made for use as diplomatic gifts or for exchange in other currencies owned by collectors.

A number of US mint employees issued stealth coins that lacked the letters on the edge, and then issued another set with the correct letters, resulting in three different denominations of the same coin.

In fact, there are only eight coins in the first-class dollar bast, and in August 1999, one was sold for $ 410,000.

The Golden Islamic Dinar
LONDON (Reuters) - An auction will be held by London's Morton & Eden auction house on October 24 to sell the gold dinar, the Daily Mail reported on Friday.

The pre-sale currency was estimated at £ 1.4 million to £ 1.6 million.

It is noteworthy that the date of issuance of this coin dates back to 723 AD, a currency made of pure gold.

Birch Cent
On September 23, 2018, CBS News reported the upcoming auction for Birch cents, of which only four pieces were minted.

It is said that Thomas Jefferson asked.

Four pieces were made, including the aforementioned coin, also called Jude-3, which has no lettering on its edges.This coin is the only known coin, knowing that it has not been sold for more than 40 years.

In January 2015, one of Birch's four cents was sold for $ 2,585,000.

Pence Abraham Lincoln made of copper
The writer reported that copper was necessary during World War II, so pennies were made of iron, and in 1943 the American Mint mistakenly issued a set of pennies made of copper, which is why if you find one of them know that the value of up to 10,000 Dollars.
