Odd stamps : 02d Silver / golden stamps

It has been a while since I posted silver and gold stamps. But today I can present you a new item from the Netherlands.

The stamp depicts Dirk Kuyt, a former Dutch football player.
Kuyt has a foundation to support G-sports (sports for mentally or physically disable people) in the Netherlands. For people with mental of physical limitations don't always find the ways to sportclubs.
The foundation helps and supports over 100 sport events as G-football, wheelchair tennis and even billiard for people with Parkinson.

The issued 'stamp' is a silver stamp, that can be used for registered mail (aangetekend).
The postal rates are currently around € 8 for registered mail, but the stamp is officially sold for € 25.

Since silver is sensitive to oxygen, the stamp is packed in a plastic cover, to prevent colour shift.
A used stamp will be hard to find, especially while it would turn black after been exposed to air.
At the time the stamp was sold in 2017, there was a limited sale of 2 'stamps' per person.
