High Tech: Holographic latent pictures on japan mint tokens

Conservation and preservation activities for natural monuments have begun in Japan and 2019 marked their 100th anniversary. The Japan Mint released a BU coin set and a proof coin set, containing special medals with the design of Special Natural Monuments of Japan, to celebrate the anniversary.

A special technology is applied on the silver medal contained in the proof coin set and a kanji character “天”, an initial letter of Natural Monuments in Japanese, appears as a holographic latent image on the obverse side when you shine an LED light (ex: a smartphone torch).
This technology is also used in other products of the Japan Mint. You can see a holographic latent image appearing by a smartphone torch light in the following video (clic here).
