20 Euros - Koningsmunt

Struck to mark the April 2013 abdication of Queen Beatrix and the accession of Willem-Alexander — the first male Dutch monarch in over a century — this piece was issued as a coronation commemorative on the day of the investiture itself. The Netherlands had not seen a king since Wilhelmina assumed the throne in 1898, making the generational shift genuinely unusual in Dutch constitutional history.

Demand on issue day was substantial enough that the Royal Dutch Mint sold out its allocation within hours.
