Description

As eye-catching, innovative and informative as its predecessors, Bionik, the exquisite purple 2012 addition to our 25 euro Silver Niobium series, pays fitting tribute to how evolution in the natural world acts as a prototype for technology.

Evolutionary pressure typically forces living organisms to become highly optimised and efficient. A prime example is the water-repellent nature of the lotus flower and of shark skin, a phenomenon fundamental in the development of paint. By the same token, the chambered shell of the nautilus has influenced architectural design and the mechanics of bird flight have clearly inspired aviation. All four of these examples feature on the coin’s obverse, while its reverse focuses on the use of bionics in architecture. A radiolarian, the plankton that inspired Spanish modernist architect Antoni GaudΓ­, is depicted in the foreground, while the reverse’s background shows an interior view of Munich’s Olympic Stadium, the roof of which was based on findings in bionics.

With a maximum mintage of 65,000 pieces in Special Uncirculated quality only, the coin contains 9 grammes of 900 fine silver in its outer ring nearly 7 grammes of 998 pure niobium. Each coin is encapsulated, boxed and comes complete with a numbered certificate guaranteeing its authenticity.
