Nikola Tesla (1856–1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist. He was born on the 10th July 1856 in the village of Smiljan, once part of the Austro-Hungarian Empire, now part of present-day Croatia. He is best remembered for his contributions to the design of the modern alternating current electricity supply system. In 1884 he moved to the United States, where he became a naturalised citizen after which he set up laboratories and companies in New York to develop a range of electrical and mechanical devices.

A geographical map of Western Europe spans the outer ring and inner core on the left side of the coin.

12 stars are located on the left side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “0” in “50.”
