"Commemorative coins are coins issued to commemorate some particular event or issue with a distinct design with reference to the occasion on which they were issued. Many coins of this category serve as collectors items only, although some countries are also issuing commemorative coins for regular circulation." - (en.wikipedia.org 29.02.2020)
