The first Dutch commemorative coin of 2016 also marks the debut of new technology
from the Royal Dutch Mint.
The Proof 2016 silver €5 coin from a series of coins honoring the
Wadden Sea will be the first Dutch commemorative coin to feature what
the Royal Dutch Mint calls the Line Phase Modulation technique.
The technique was used to highlight seagulls flying over a map of
the sea's islands on the reverse of the coin.

In this technique, an existing image is converted to a line pattern.
The distance between the individual lines varies, creating the
appearance of gray shading. The image is best viewed when tilting the
coin, as the wavy lines glitter across the birds in flight.
This coin is part of an annual series celebrating the UNESCO World
Heritage Sites in the Netherlands. The 2016 program is the fifth in
The Wadden Sea is an intertidal zone in the southeastern part of the
North Sea. It lies between the coast of northwestern continental
Europe and the range of Frisian Islands, forming a shallow body of
water with tidal flats and wetlands. It is rich in biological diversity.
In 2009, the Dutch and German parts of the Wadden Sea were inscribed
on UNESCO’s World Heritage List and the Danish part was added in June
2014. The German part was the setting for the 1903 Erskine Childers
novel The Riddle of the Sands.
The Wadden Sea coins were designed by Kianoosh Motallebi.
Base-metal and silver examples are denominated €5, and a gold €10
coin completes the program.
On the obverse is a map of the region with identifying place names,
along with local wildlife.
The reverse carries the portrait of King Willem-Alexander.
Multiple metals, finishes and denominations are available.

PostNL post offices, Primera shops and the Royal Dutch Mint website
