The vision of the euro masks comes from a dream. A friend lowered me by the feet into a dark bottomless pit. Luckily I had a flashlight and saw a series of ancient cave paintings on the walls. Pointing the ray of light into the abyss, I saw the coin as a mask, spiraling up towards me like a meteor. Upon waking,  I immediately began to search through the 150 kilos of destroyed euro coins, and after a week, I found the coin ( middle image first row) and then persevered to find others.
