wow really awesome
it is a nice idea to enhance such a piece
I think several "options" can be printed also for other coins as suggested by @Kryptowerk
Just fit the "pocket" where the coin rests and it's over...
However the idea/design it reminds to me "Uncle Scrooge" and his "Number one" (Zio Paperone e la Numero Uno)...
I hope for @gbianchi this is the first piece of a long series and this is just a start
