A stylised profile of King William-Alexander surrounded by 12 stars. The effigy is separated in two parts by an area with a vertical line. At the left of the vertical line, reading from bottom to top, the mark of the National Mint Director, the text "Willem-Alexander" and the Royal Dutch Mint mark. At the right of the vertical line, reading from top to bottom, the title "King of the Netherlands" in Dutch. At the bottom left of the effigy the year of issuance.

Mint mark: Caduceus (Mercury's wand, a short staff entwined by two serpents, sometimes surmounted by wings), the logo of the Royal Dutch Mint (Utrecht, the Netherlands)

Mint master mark: sailboat+star (Ted Peters, 2017)

The star indicates that the piece was struck at the beginning of the term of office of a successor.

Engraver: Erwin Olaf

The coin’s numeral of “50” euro-cent has an Orange color, symbolic for the Dutch National team whose colors are also orange and the name of reigning royal dynasty (Orange-Nassau).

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.”
