The Mint of Japan has unveiled its 2020 collection of Proof and mint sets which include presentation folders for special occasions. The 2020-dated sets include the denotation of the second year of Reiwa, named after Emperor Naruhito’s regnal era, which began in May 2019.
500-Yen Nickel-Brass Coin, 2000–2020
This year marks the 20th year since the current 500-yen nickel-brass coin was issued. The coin, which incorporated four types of anti-counterfeiting technology such as latent imaging, helical ridges, microdots, and micro stripes, was first minted in 2000. A new bi-metallic 500-yen coin will be minted incorporating new anti-counterfeiting measures, and this will be issued from the first half of 2021.
Each coin set includes the currently circulating denominations from one to 500-yen, and all six coins are accompanied by a special collector medal that is determined by the set’s theme. There is an option to acquire the Proof set medal in the presentation or choose a Proof set that omits its inclusion.
