One of two designs of a commemorative coin issued in 1979 by Switzerland to mark the centennial of Einstein's birth. The coin is in a red leather box with the symbol of the Swiss flag, a cross, on the inside of the box lid. This 5-franc piece says "Confoederatio Helvetica 5 FR 1979" on one side, and the reverse of this design version features the text "Albert Einstein" and two equations. Einstein became a Swiss citizen later in life, and his connection to that country began as a student at a Swiss secondary school and continued into his adulthood.
