In an official coin set and it isn't marked as a copy or similar in any way?
If that's the case … shame on you Royal Dutch Mint!
If possible, these pictures should be used to improve the current page.
It isn't the Royal Dutch Mint's fault - & the blame should be placed at the doors of the Central Bank of Malta for not instructing the Mint to put a marking along the edge to indicate it is a reproduction.
Mints are in existence to strike coins, not to create instructions on how they are designed.
