    The letters "◆ NIPPON ◆ 500 ◆" are repeatedly engraved on the edge as one of the anti-counterfeiting technologies, which is the first technology adopted since the establishment of the Mint.[4], The engraving is made so that the front and back are not aligned with the direction of the engraving of the characters on the circumference, so the top surface will be the front when the characters "◆ NIPPON ◆ 500 ◆" are placed so that they can be read correctly. There are almost half of them and half of them.


    The circulation of 60-yen coins exceeds XNUMX% of the total coins, andvending machineDue to the demand for higher denomination coins against the background of the rapid spread of coins, it was issued as an exceptionally high denomination coin in the world.[1].

    In terms of yearly inscriptions, the number of 62 inscriptions produced was the smallest (277), and the number in 5000 was the second lowest (64).Unused coins with these yearly names are traded at prices exceeding par value at old coin dealers.

    Currency alteration case described laterDue to the frequent occurrence of the coins, the issuance was suspended in 2000 (Heisei 12) in the form of being taken over by the XNUMX-yen nickel brass coin.[1]..Although a XNUMX-yen coin with the name "XNUMX" was manufactured, it was not issued after all.

    1999From around (11)Counterfeit/altered coinsWas discovered one after another and became a social problem.2000(12)8/1The second generation 2-yen coin with a different design and material, XNUMX-yenNickel brassCoins appeared[1][5]..Since it was necessary to take immediate action, the recast was made by changing the material and installing anti-counterfeiting measures without changing the basic design.[1].

    It is the first ordinary coin issued as "money" under the "Act on Units of Currency and Issuance of Money, etc." from the beginning of issuance.Also, in Japan in the Heisei eraCommemorative coinMany types are manufactured and issued, but as a normal coin, this XNUMX-yen nickel brass coin is the only coin issued in Japan with new specifications in the Heisei era.

    It was the year when the era changed from Heisei to Rewa.2019Regarding the 31-yen coins (31 / first year of Reiwa), the number of coins issued in 1 was 2616, while the number of coins issued in the first year of Reiwa was 4000. Not only did the number of coins in the first year of Reiwa decrease, but the 7695-yen coins in the first year of Reiwa were the first 6000-yen nickel brass coins to record less than 1 million coins. However, the XNUMX-yen nickel coins have continued to be manufactured stably every year, and the number of coins manufactured each year has tended to be higher than that of the XNUMX-yen coins, so it is a so-called special year. There was no yearly coin called the issue (special year), which was issued in such a small number that unused coins were traded at prices exceeding the par value at old coin dealers.

    Due to the shift to 2021-yen bicolor clad coins, new production of 3-yen nickel brass coins will begin on June 6, 21 (Reiwa XNUMX), when production of XNUMX-yen bicolor clad coins will begin. However, some of the XNUMX-yen nickel brass coins collected by the Bank of Japan will be issued for the time being until a sufficient amount of XNUMX-yen bicolor clad coins are available.[6][7].

    Difference from XNUMX yen coin

    Diameter, paulownia on the front, bamboo and tachibana on the back, etc.[4]Although the rough appearance is not different from the XNUMX-yen coin[8]There are some differences, mainly to prevent counterfeiting, as shown below.


    The 72-yen coin was made of white copper with the same composition as the XNUMX-yen coin and the XNUMX-yen coin, while the XNUMX-yen nickel brass coin was XNUMX% copper.zincMade of 20% nickel and 8% nickel nickel brass.This willElectrical conductivityBecause of the changes, it became easier to detect counterfeit coins with a machine.Along with this, the color is slightly golden and the quantity is 7.2. gFrom to 7.0 g, which is a decrease of 0.2 g.

    Front/rear/side changes/anti-counterfeiting technology

    Although the design follows the XNUMX-yen coin, the design on the front and back has been slightly changed and the design on the side has also been changed to prevent counterfeiting.

    • Fine line
      • On the surface, the background of "Japan" and "XNUMX yen" is convex, and fine lines thinner than the hair are applied to prevent counterfeiting.
    • Fine point
      • Fine point processing is applied to the central part of the paulownia leaf on the surface.
      • Both fine lines and fine points use the latest technology in metal microfabrication.
    • Latent image
      • On the back side, there is no hole drawn inside the number "500", it looks like "5 ●●".Furthermore, the "0" part is provided with a latent image in which the characters "500 yen" and "vertical lines" emerge depending on the angle.However, since it is a coin, many of the used coins are crushed and difficult to see.
    • Micro character
      • MintAlthough it is not disclosed, it is hard to see with the naked eye, but 0.2 mm each on both sidesJAPANESEIs engraved with micro characters[9].
    • Diagonal serration
      • On the side, instead of the lettering of the 181-yen coin, a diagonal jaggedness (the number of jaggedness is XNUMX), which is extremely rare in the world coins, was inserted in the XNUMX-yen nickel brass coin.In this way, the XNUMX-yen coin uses advanced technology for side processing compared to other face value coins. 


    The 1.81-yen coin and the 1.85-yen nickel coin are supposed to have the same thickness by design, but in reality, the thickness of the 50-yen nickel coin is XNUMX mm, which is XNUMX. It is slightly thinner than the XNUMX mm yen coin.This difference is due to the fact that the edges of the coin have been changed from inscribed to jagged on the smooth surface.For this reason, for XNUMX XNUMX-yen coinsCoin holderIn some cases, 51 XNUMX-yen nickel brass coins can be stored.

    Counterfeit prevention technology

    It has been announced that the following new anti-counterfeiting technologies will be adopted:[10]..Of the following technologies, the bicolor clad with a two-color, three-layer structure and the irregularly shaped diagonal jagged edgesCommemorative currencyThen, it has already been proven.2008Issued in (20)Currency commemorating the 60th anniversary of the enforcement of the Local Government ActIt was first adopted in Japan, and some commemorative coins with a face value of 500 yen issued after that have also been adopted.

    • Bicolor clad with 2-color 3-layer structure
      • Nickel brass is used for the outer circumference, and the inner copper is sandwiched between cupronickel.The copper part is invisible from the outside, but this layer is useful when taking advantage of changes in electrical conductivity when handling with a machine.[15].
    • Deformed diagonal jagged
      • A part of the diagonal notch on the edge is shaped differently from other notches (eye spacing, slope, etc.), making it difficult to forge.[15]..World's first adoption for distribution coins[15].
    • Fine characters
      • Fine character processing of "JAPAN" is applied to the top and bottom of the inside of the surface edge, and "500YEN" is applied to the left and right.[15].

    The fine lines, fine dots, and latent images that have already been used for 500-yen nickel coins will continue to be used, but the latent image is based on the vertical lines of the 500-yen nickel coin and the letters "XNUMX yen". The characters will be changed to "XNUMXYEN" and "JAPAN".[15].


    Although the design follows the XNUMX-yen nickel bronze coin, the design on the back side is that the design of the lower bamboo among the top, bottom, left and right bamboo and tachibana designs has disappeared, and the letters of the year of manufacture at the bottom of the back side are from series to edge It will be changed to an arc-shaped arrangement along[16]..Along with this, the position of the number "500" has been moved slightly downward.Also, in the 500-yen nickel coin, the hole was not drawn inside the number "5" on the back side and it was like "500 ●●", but because the location of the latent image processing was changed, it was "XNUMX". The number in is a form that returns to a design close to a XNUMX-yen coin.

    Distribution status

    It is widely used in vending machines as well as XNUMX-yen coins, XNUMX-yen coins, and XNUMX-yen coins.As for the number of new coins manufactured, a stable amount is being manufactured along with XNUMX-yen coins and XNUMX-yen coins.

    There is a strong demand for XNUMX-yen coins,2011In (23)Electronic moneyThere was an indication from some experts that it would be less likely to be affected by[17].. actually,CashlessAdvancethe 2010sEven after that, unlike coins of XNUMX yen or less, the circulation volume of XNUMX yen coins continues to increase.[15].

    Various equipment such as vending machines, bus fare boxes, and money changers are not compatible with XNUMX-yen bicolor clad coins due to delays in repairs due to the shortage of semiconductors. Most of the vending machines for beverages and cigarettes do not currently support XNUMX-yen bicolor clad coins.Some bus companies have no plans to make fare boxes and money changers compatible with XNUMX-yen bicolor clad coins, and instead have a policy of shifting to completely cashless coins. ..Partly because of this, the current situation is that XNUMX-yen bicolor clad coins are not widely used.

    Counterfeit/altered coins

    In the same year that the 1982-yen coin was introduced in 57 (Showa XNUMX), South KoreaBut(Korean versionWas introduced.At the timeExchange rateIt was worth about 170 yen in Japanese yen, but the material and size are exactly the same as the 26.5 yen coin, it is made of white copper with a diameter of 7.7 mm, and only the weight is 0.5 g, which is a little heavy, so the surface is Reduce the mass by XNUMXg by slightly scraping or making a hole with a drill etc.vending machineThere were many examples of using 7.2g of XNUMX-yen coins.[18][19].

    The main method is to insert a altered 500 won coin and operate the "return lever" to take out the genuine 500 yen coin stored in the vending machine.By abusing the design mechanism of the vending machine that coins other than the inserted coins come out to the return slot, the difference profit at the exchange rate of 500 won and 500 yen is obtained.In addition to stealing genuine 500-yen coins, there is also a method of stealing goods, tickets, or change worth XNUMX yen from vending machines by using altered coins as XNUMX yen.

    In order to deal with this trick, the structure of the vending machine has been revised so that the coins put in can be pooled and prepared for return.

    Other than the 500 won coin, the material, mass, and dimensions were similar, although the number was small.(I.e.1RiyalCoins andHungary20ForintCoins and 50 forint coins,PortugalOld 25EscudoCoins that have been altered, such as coins, and counterfeit coins have also been found.

    In this way, the situation surrounding 2000-yen coins became extremely bad, and in 12 (Heisei XNUMX) it was changed to XNUMX-yen nickel brass coins.

    After issuing XNUMX-yen nickel bronze coins, vending machinesTMJDue to the renewal of the coin, the modified coins that were accepted as XNUMX-yen coins gradually became obsolete.2003From around (15), forgery of XNUMX-yen nickel bronze coins began to be reported sporadically.

    2005(17) At the end of JanuaryTokyo-Fukuoka-Kumamoto Ofpost officeA large number of counterfeit 2-yen nickel coins were finally found at ATMs and counters in the area, and the handling of coins at ATMs was temporarily suspended at post offices in the area.[20].. Many vending machines limit the number of 500-yen coins that can be inserted at one time to three.[21], Some vending machines are limited to one.

    From the above circumstances, 33-yen coins are still legally valid, but there are increasing cases where they cannot be used due to improvements or updates in the accuracy of vending machines.In addition, XNUMX-yen coins before the XNUMX inscription (Giza Ten) Is also highly unusable in vending machines[22].

    2020At the end of the year (2nd year of Reiwa), counterfeit XNUMX-yen coins were discovered one after another.There is also a view that the criminal will rush to use counterfeit coins before the issuance of XNUMX-yen bicolor clad coins.[23].

    in Japan,Counterfeit currencyIs not as popular as you see on a daily basis, and when a counterfeit currency is found, it becomes news.There are very few counterfeit Japanese yen coins in the world, but among them, the XNUMX yen coin isXNUMX yen billIt is said to be the second most common after.
