The 500 yen coin (Japanese: 五百円硬貨, Hepburn: Gohyaku-en kōka) is the largest denomination of Japanese yen coin issued for circulation. These coins were first struck in 1982 as the vending machine industry needed a higher valued coin for use in their machines. The denomination had previously been issued as paper currency which co-circulated with the new coins until 1994. Originally the 500 yen coin was made up of cupronickel, but was later changed to nickel brass, and then to bi-metallic to deter counterfeiting. This illegal practice has been a constant issue since the coin was first released due to its high purchase value. With a history spanning 3 imperial eras, 500 yen coins are also collectibles.
