Money-collectors generally refer to ordinary coins that are usually the most common and have a low price. They are often used as garbage coins. Most of the money collectors often disregard the garbage. In fact, ordinary coins are not ordinary, and the ingenious collection of garbage coins can also be appreciated. Very common common coins can be upgraded into treasures after being copied.
There is a coin collector who likes to collect coins in circulation around the world. At a coin fair, he showed two sets of seemingly ordinary coins, one for the full year of Hong Kong dollars and one cent, and the other for the full year of the dollar. These two sets of coins made everyone in the audience stunned. It is said that no one has been able to fully collect the two sets of coins before this. One of the 1941 Hong Kong dollars and one centurion was extremely small. At that time, it was worth more than 20,000 yuan. The value of the whole set of coins is incalculable.
The number of 1st, 2nd, and 5th notes in the renminbi can be said to be everywhere in the past few years. Many people may never have thought that such a large amount of paper money can also appreciate. In fact, some mindy money collectors have long been collecting these paper cents. They are collected according to the serial number of the Roman numerals on the ticket. It is now known that there are 231 cents in the Roman numerals, and 89 in the Roman numerals. There are 129, 5 cents, and 3 Roman numerals in the Romans. There are 64, a total of 513 kinds. The market price of these 513 kinds of papers with different Roman numbers is as high as tens of thousands.
The common coins in ancient coins are also worth collecting. Taking Wuyi as an example, from Han to Yu, in the history of more than 600 years, the five cents of money were repeatedly cast year after year, and the number passed down was very alarming. In the market, these coins are also the cheapest, each only 1 to 2 yuan. One coin collector found that although the text of the five-dollar money is unchanged, the calligraphy style of the text is endless, so the five-dollar money of various editions is collected. After years of accumulation, there are various versions. There are more than 200 kinds. Once a Japanese collector saw his collection and even claimed that he was willing to buy at a high price, but he did not want to cut love.
There are also some very common copper collections that can be surprisingly successful. In the coin market, the copper yuan garbage coin only sells one to two yuan, such as a certain kind of "Guangxu yuanbao" copper yuan, you can find out by careful observation that each "Guangxu ingot" from dragons to dragon claws and dragon tails; From the decoration to the moiré and the star point, almost every copper element has many different editions. If you can be a thoughtful person and collect 30 ordinary copper coins of the same variety but different editions, then the value can reach More than a thousand dollars.
